Installation
This section describes how to install and operate the WFM 601A, WFM 601E,
and WFM 601M Serial Digital Component Waveform Monitors. It also describes
how to remove the waveform monitors for servicing. Note that repackaging
information is located at the end of the Maintenance section.
This manual includes one 3.5-inch high-density floppy disk that contains service
software. This software is used for the adjustment procedure. Instructions for
using the disk are located in the Adjustment Procedure section of this manual.
Hardware Installation
Because operating environments vary, the waveform monitor is not shipped with
a cabinet unless one is ordered. All qualification testing for the waveform
monitor was performed in a 1700F00 cabinet. To guarantee compliance with
specifications, you should operate the waveform monitor in one of the cabinets
described here.
WARNING. When power is supplied to the rear panel, line voltage is still present
in the instrument, even if the Power switch LED is off.
Cabinets
The cabinets offered for the waveform monitor provide EMI shielding, protect
against electrical shock, and protect against the accumulation of dust.
A rear panel fan supplies filtered, cooling air which exits through the cabinet
vent holes. Restricting the air flow through the vents or the rear fan can lead to an
excessive internal temperature. To ensure adequate ventilation, provide the
following clearance for the waveform monitor: three inches at the rear, two
inches on each side, and one inch each on the top and and the bottom.
NOTE. To meet EMI emission specifications, the waveform monitors must be
installed in a Tektronix 1700F00, 1700F02, or 1700F05 cabinet. The cabinet
front edges must securely contact the conductive front bezel on all four sides.

The component serial digital video signal is buffered and applied to the Serial
Receiver circuit. An unbuffered version of the digital signal is routed to the Eye
Sampler circuit. The Serial Receiver contains a phase-locked loop circuit that
locks its clock to the incoming 270 MHz data signal. Jumper P13 is normally on
pins 2 and 3, which selects a clock adjust circuit that brings the oscillator close to
the incoming frequency so the PLL can operate. With P13 on pins 1 and 2, you
can adjust R269 to change the oscillator center frequency. If you remove cable J3
from the DAC board for troubleshooting, you can move P13 to pins 1 and 2 and
adjust R269 to lock on the incoming signal.
If the input signal amplitude is low, the Serial Receiver provides equalization by
boosting the high-frequency components of the signal. A Cable Driver circuit
buffers the reclocked serial digital signal for the Serial Out rear-panel output. A
divide by 10 circuit provides the 27 MHz clock for the Eye pattern circuit. An
A/D converter digitizes various analog inputs under microprocessor control.
Jitter Demodulator and
Peak Detectors
The Jitter Demodulator is a phase detector that receives a reference clock and the
27 MHz clock derived from the input signal. The output is a Jitter signal for
display, measurement, and export to the rear panel Jitter output. The Peak
Detector circuit splits the incoming Jitter signal into two paths: the high-pass
peak detector and the raw peak detector. The selected high-pass filter is applied

Block Diagram Descriptions
to the jitter signal then sent to the positive and negative peak detectors. The DC
outputs of these detectors connect to the A/D converter. The unfiltered Jitter
signal is separately peak detected and the DC outputs connected to the A/D
converter. The Jitter circuit includes a switch that selects between the Jitter signal
and the sampled Eye signal for display.
Signal Level Meter
Eye Pattern Sampler
Coprocessor
The Signal Level Meter compares the amplitude of the serial digital signal at
10 MHz and 77 MHz. The amplitude at each of the frequencies is output as a
logarithmic DC voltage to the A/D converter. The microprocessor compares
these levels to determine the cable length measurement.
The Eye Pattern circuit is an equivalent-time sampler that allows viewing of the
serial bit stream as a voltage-versus-time signal. Using a phase locked oscillator,
the sample clock (6.75 MHz) is derived from the 27 MHz Parallel Clock and
horizontal line frequency (FH) signals. The input signal is displayed either with
serial receiver equalization (Eq Eye) or without (Eye).
The Coprocessor receives 10 bit parallel video input from the Deserializer, the
recovered 27 MHz clock, and control instructions from the microprocessor. The
coprocessor performs gamut and format error checking on the component video.
Three horizontal lines of the component video data are stored in a buffer RAM
for the Digital Data displays. The coprocessor outputs the clocks and 10 bit
interleaved video data to enable the recovery of the Y, R–Y and B–Y signals by
the Half Band filters and DACs. In addition, it generates the signals used for
clamping, to re-establish the vertical blanking interval, and to provide composite
synchronization. The coprocessor removes nonvideo data from the signal, such as
end of active video (EAV), start of active video (SAV), and ancillary data.
Deserializer
The Deserializer receives the 270 MHz component serial data and the recovered
parallel clock. The output is 10 bit video component data for the coprocessor.
Phase Locked Loop and
Clock Regenerator
The Phase Locked Loop circuit synchronizes an oscillator circuit with the
recovered 27 MHz clock. A switch circuit allows selection of the direct
recovered clock or the onboard 27 MHz clock, which appears as the front-panel
selection CONFIG–FORMAT–SYNC AFC.
Y Delay, Half-Band Filters,
and DACs
The multiplexed video data stream from the coprocessor is converted to analog
components by three digital-to-analog converters (DACs). The Y Delay circuit
delays the luminance data to ensure it passes through the Half Band filter and
DAC properly synchronized with the chrominance signals. The coprocessor
generates the clock and timing enable signals for the luminance and two color
difference Half Band filters and DACs.

Block Diagram Descriptions
The Half Band filters (HBF) use interpolation to double the number of data
values in order to ensure a smoother product from the DACs. Data timing signals
are 13.5 MHz for luminance and 6.75 MHz for color difference. The HBFs are
clocked at 27 MHz for luminance (Y) and 13.5 MHz for Pb and Pr signals. Data
out of the HBFs are input to three DACs. The DAC outputs are the component
analog signals, Y, Pb, and Pr. Their gain and DC offset is set by the microprocessor through a Daculator on the Component board, diagram 12.
Y, Pb and Pr
Reconstruction Filters
The three separate Reconstruction Filters are bandpass filters that provide
adjustments for matching the delay through the three HB filters, DACs and
Reconstruction filters. An adjustable offset is added to each signal as required for
display.
Input Multiplexer
The Line Rate Controller dictates the selection of display when color difference
or RGB signals are being displayed. The output of the multiplexer drives the Flat,
Luminance, and Differentiated Step Inputs of the Filter Multiplexer.
Filter Selection

Square Wave Calibrator
The calibrator provides a 700 mV, 100 kHz output. Its amplitude is set by a
microprocessor-controlled DAC, and its timing is set by the Line Rate Controller.
Vertical Amplifier
The Vertical Amplifier is a variable gain amplifier that has controlling inputs
driven by either microprocessor or synchronous Line Rate Controller outputs.
Stage gain is controlled by the DAC output voltages. The Line Rate Controller
selects and enables vertical magnification.
An offset voltage from the DACs vertically positions the display. When CRT
readout processing occurs, the Line Rate Controller changes the gain of the
amplifier. The differential output of the Vertical Amplifier drives the vertical
output amplifier, which powers the CRT deflection plates.

Switch
Sweep Generators and
Horizontal Signal
Multiplexer
The Horizontal Reference Multiplexer selects either the COMPSYNC signal

signals from the Line Rate Controller. The microprocessor controls the Sweep
ramp times, which are 17 ms for the field sweep and 64 ms for the line sweep.

Horizontal Amplifier
The Horizontal Amplifier is a variable gain amplifier with controlling inputs
from the microprocessor and Line Rate Controller. Stage gain is controlled by the
DAC output voltages. The Line Rate Controller selects the magnification gain.
An offset voltage horizontally positions the display. The amount of offset
required for the Waveform mode is significantly greater than that required for the
other display modes. During processing of the CRT readout, the Line Rate
Controller changes the gain of the amplifier as necessary.
The differential output of the Horizontal Amplifier drives the horizontal output
amplifier which powers the CRT deflection plates.
An additional amplifier stage within the Horizontal Amplifier provides a
differential output that controls the intensity for the Picture Monitor mode. The
microprocessor controls the Picture Monitor contrast.
Blanking Logic
The Blanking Logic is a multiplexer, which is controlled by the Line Rate
Controller. The Blanking Logic selects the blanking/unblanking signals that drive

Switch output is buffered and becomes the input to the Color Difference to GBR
Transcoder, Bypass Switching, and Component display mode switching.
The three component signals enter three mixers that produce GBR signals
according to the SMPTE format. An adjustable offset is added to each signal as
required for display.
The Switch Control Buffers select either the color difference input signals or the
transcoded GBR signals to drive the Picture Monitor Output amplifiers.
The Gamut Limit Comparator includes separate circuits to compare the GBR
signals and the component signals to the user selected gamut limits. The two
comparators generate separate GBR and composite gamut alarm signals. When
the signal exceeds the GBR gamut limits, the Monitor output flashes. A gamut

switching provides the vertical and horizontal axes inputs for Lightning,
Diamond, Component Vector, and Bowtie displays. The microprocessor controls
the display switching through the Controller circuit.
Block Diagram 3, Microprocessor and Control
Microprocessor
The microprocessor has a 32 bit internal architecture and a 16-bit data bus. At
boot up it reads initial code from the Read-Only Memory (ROM). The microprocessor then loads program code from EPROM into the RAM for execution. The
Nonvolatile Random Access Memory (NVRAM) stores all the calibration and
other constants used by the microprocessor.
The 24 bit Address Buffer is unidirectional and is used to select the addresses in
the storage devices (RAM, ROM, and EPROM). The Data Buffer is bidirectional. The flash EPROM is programmed through the RS-232 port.
Line Rate Controller
and FIFO
The Line Rate Controller (LRC) is a custom IC that loads information from
ROM at power up. The microprocessor controls the LRC by placing commands
in the FIFO which the LRC reads. The LRC uses three clock inputs (5.5, 6, and
16 MHz) and the H sync pulse to synchronize to the incoming video reference
and to generate synchronous switching signals required to drive the various
displays modes.
Sync Separator
The Sync Separator strips the sync pulses from either the internal video signal or
the external reference video. It generates H sync and V sync to synchronize the
Line Rate Controller.
Synchronous Outputs
Data and control signals from the microprocessor are loaded into latches clocked
by the Line Rate Controller, which lock their outputs to the incoming video
signal.
Readout State Machine
The Readout State Machine interprets the readout instructions from the microprocessor and loads digital data into two identical DACs. The DACs drive the
vertical and horizontal stroke generators to create the readouts displayed on the
CRT.

Serial Static Outputs
Serial Interface
The microprocessor controls this serial in/parallel out register. It outputs control
signals that are not synchronized to the video signal.
The Serial Interface is a latch, driven by the microprocessor, that outputs the chip

registers used for the Remote and Front Panel.
Digital-to-Analog
Converter (DAC)
There are a number of DACs used to decode microprocessor instructions and
output positioning, gain, and DC offsets to many instrument circuits. These
DACs are serially loaded and clocked devices, which are commonly referred to
as Daculators. The DACs have 15 outputs each that hold their programmed
output once it is set.
RS232
The RS-232 input consists of a 9-pin D connector and a line driver. It is used to
calibrate the instrument and for remote control using the remote command set.
Remote
The Remote input consists of a 25-pin D connector and parallel in/serial out
registers. The Remote interface provides an external interface for low-level
remote control of the waveform monitors.
Power Supplies
The low-voltage power supply is of the switching, high efficiency type. It is a
universal supply that operates over an AC source range of 90 to 250 VAC. The
high-voltage power supply provides an acceleration potential of approximately
13.75 kV. Figure 3–1 provides a block diagram of the power supply.

Block Diagram Descriptions
The following discussion covers the main blocks on the A1 Power Supply
schematics.
Primary Side
Line power enters through an RF filter on the rear panel. The Line Rectifier
circuit correctly converts 90 to 250 VAC. The line voltage or primary side of the
power supply is fully isolated from the secondary or DC side by transformers and
optical signal isolators.
Initial power conversion is controlled by a current-mode pulse width modulator
circuit centered on U6. The switcher operates at 100 kHz. U6 senses the output
voltage level from U4 and a ramp voltage representing the current in the
transformer switcher, Q14. On power up, C62 accumulates a trickle charge to
16 V, which powers U6.
When the power switch is set to on, the 170 kHz oscillation on the Power Switch
Oscillator (Q13 and T2) stops, causing the Mag Latch to switch state. The Mag
Latch remembers its state mechanically. The output of the Mag Latch is summed
with the output of the Overload Time-out to enable or disable the Controller. A
shutdown occurs within a few milliseconds and lasts 1 second. The Snubber
circuit clamps any voltage that exceeds twice the rectified power line input.
Secondary Side
The secondary circuits include the low voltage output filters and error detection.
The Error Amplifier signals the Controller to help regulate the +5 V supply. The
5 V adjustment is in this circuit. The Overvoltage Protection circuit monitors the
+5 V supply and grounds the 5 V supply if it rises above 5.5 V. The –5.2 V
supply can signal an over-voltage condition through Q21 and ground the 5 V
supply. The power supply goes through its start up sequence after this grounding.
LED DS6 indicates the 5 V supply is on.
The Output Filters rectify the T1 secondary windings and filters the low voltage
outputs. The exception here is the –5.2 V Buck circuit. It provides regulated
–5.2 V from the –11 V supply. U10 is the pulse width modulator that operates
similar to U6 on the primary side. The 100 kHz out of U10 drives Q18 with a
varying duty cycle that produces a DC average out of L10. An input from the
+5 V secondary helps synchronize the 100 kHz oscillator to the Primary side.
High Voltage Supply
The High Voltage Power Supply is generated by a sine-wave oscillator and
step-up transformer. The main components of the high-voltage oscillator and
error amplifier circuit are Q7 and T3, which form an Armstrong oscillator
running at about 22 kHz. Error amplifier U2 regulates the +100 V output and
keeps the High Voltage Power Supply constant under varying load conditions by
controlling the base current to Q7. C26 and Q8 delays the start up of the
high-voltage supply until the Low Voltage supply is running.
The CRT cathode supply consists of rectifier CR7 and filtering capacitors. The
supply provides –2530 V to the CRT cathode. U1 is a four-times multiplier

Block Diagram Descriptions
providing +11 kV to the CRT anode. The grid is approximately 75 V negative
with respect to the cathode.
Low frequency blanking information gets to the CRT grid through an amplitude
modulated 200 Vp-p sine wave from the anode of CR15. Positive level clipping is
set by the CRT Bias adjustment, R53. Negative clipping level is set by the
front-panel INTENSITY control through the Z-Axis Amplifier. The clipped sine
wave is rectified to a DC voltage proportional to the peak-to-peak amplitude and
becomes the CRT control grid bias voltage. DS4 limits the CRT heater to the
cathode voltage.
The Z Axis Amplifier takes a signal from the Main board into the junction of
R10 and R5, which is the summing junction for the amplifier. It is at +5 VDC. R5
is a feedback resistor, which sets the amplifier gain at 36 V/mA of input current.

Out Gain Accuracy, differs greatly between models, different versions of the
procedure occur sequentially. Choose the one that pertains to the waveform
monitor under test. Test equipment used in this procedure should be operating
correctly and within calibration.
Perform the Performance Verification procedure at regular intervals to ensure
that instrument performance is within tolerance. The recommended interval for
performance verification is 2000 hours of operation or every 12 months.

grounding straps. Service static-sensitive assemblies or components only at a
static-free workstation.
WFM 601A, WFM 601E, & WFM 601M Service Manual
Maintenance
H
Keep static generating items or items capable of holding a static charge away
from the workstation surface.
H
Keep the component leads shorted together whenever possible.
H
Pick up the components by the body, never by the leads.
H
Always move components by picking them up first, never by sliding them
across a surface.
H
Avoid handling components in areas that have a floor or work surface
covering capable of generating a static charge.
H
Use a soldering iron that is connected to earth ground.
H
Use only antistatic suction or wick-type desoldering tools.
Inspection and Cleaning
Clean the instrument often enough to prevent dust or dirt from accumulating. Dirt
acts as an insulating blanket that prevents effective heat dissipation and can
provide electrical leakage paths between conductors or components in a humid
environment.
CAUTION. Do not allow water to get inside enclosed assemblies or components.
Do not clean plastic materials with organic cleaning solvents, such as benzene,
toluene, xylene, acetone, or similar compounds, because they may damage the
plastic.
Cleaning the Exterior
Cleaning the CRT/Display
Cleaning the Interior
Clean the dust from the exterior of the instrument by wiping it with a soft cloth
or small brush. A brush is useful to remove dust from around the buttons, knobs,
and connectors. Remove hardened dirt with a cloth dampened in water containing a mild detergent. Do not use abrasive cleaners.
Clean the CRT protective shield, light filter, and CRT face with a soft, lint-free
cloth dampened in denatured alcohol.
Clean the interior of the instrument by loosening the accumulated dust with a dry,
soft brush. Once the dirt is loose, remove it with low-pressure air. High-velocity
air can damage parts. Remove hardened dirt or grease with a cotton-tipped
applicator dampened with a solution of mild detergent and water. Abrasive
cleaners should not be used. If the circuit board assemblies must be removed for
cleaning, refer to Removal and Replacement on page 6–5.
WFM 601A, WFM 601E, & WFM 601M Service Manual
6–3
Maintenance
After cleaning, allow the interior to thoroughly dry before applying power to the
instrument.
Replacing and Cleaning
the Air Filter
In order to operate in all environmental conditions the waveform monitor
requires clean unrestricted air flow. The air filter, which cleans the air supplied
by the fan, is located in the fan housing on the rear panel. Check the filter
frequently. A supply of replacement filters was shipped with this instrument.
Filter Replacement. To replace the air filter, pull the fan cover off the fan, lift out
the old filter and replace it. Carefully press the cover into place over the fan
housing. Refer to Figure 6–14 on page 6–16 for details of the fan assembly.
Filter Cleaning. You can clean and reuse the air filters supplied with this instrument. Wash the used filters in warm water and mild detergent. Let them dry
thoroughly before reusing them.
Additional Air Filters. Order additional air filters directly from Tektronix. The part
number for the air filters is listed in Options, section 7.
Visual Inspection
After cleaning, carefully check the instrument for defective connections or
damaged parts. If you discover a heat-damaged part, determine the cause of
overheating before replacing the damaged part to prevent additional damage.
Periodic checks of the transistors and integrated circuits are not recommended.
The best measure of performance is the actual operation of the component in the
circuit.
Determining the Software
Version
Operation of the waveform monitors is dependent upon the operating software
loaded in the Flash EPROM on the Main board. New software versions may be
released to add features or correct reported problems. You can save considerable
time and troubleshooting effort by reporting the software version when calling
Tektronix for parts or service information.
NOTE. If the Flash EPROM fails, you will need to return the instrument to
Tektronix to replace the part and restore proper operation.

Troubleshooting
This section describes the how to troubleshoot the waveform monitor. Following
a general discussion of techniques, specific procedures are given for replacing
the fuse, troubleshooting the Power Supply and configuring the Component and
DAC boards for troubleshooting.
General Troubleshooting
Techniques
The following procedure is designed to help you isolate problems, which
expedites repairs and minimizes down time.
1. Determine if the malfunction exists in the waveform monitor or in another
system component. Make sure that the waveform monitor is being correctly
operated as intended by Tektronix (see Operating Instructions). Check that an
instrument upstream from the waveform monitor is not malfunctioning.
2. Determine and evaluate all trouble symptoms. Isolate the problem to a
functional block, assembly, or circuit board. Use the Theory of Operation in
section 3 and the block diagrams in section 9 for tracing signals and isolating
circuits.
CAUTION. To avoid damaging components, use care when probing with meter
leads or probes. Misplacing leads or a probe could cause a short circuit or
transient voltage capable of destroying components.
3. Determine the nature of the problem. Try to determine whether the waveform
monitor is out of calibration or if there has been a component failure. Once
the type of failure has been determined, identify the functional area most
likely at fault.
4. Inspect the suspect assembly for physical defects. Most commonly these will
be components that are broken or loose, improperly seated, or overheated or
burned. Chafed insulation is also a common physical defect. Refer to the
Power Supply troubleshooting procedure on page 6–26. Repair or replace
obvious defects. In the case of overheated components, determine the cause
of overheating and correct the cause before re-applying power.
5. Use successive electrical checks to locate the source of the problem. The best
tool for isolating problems is the oscilloscope. Use the Performance
Verification procedure to check if a circuit is operating within specifications.
6. If the waveform monitor is operating, you should attempt to save the
calibration information into an NVDATA.TXT file using the Upgrade
program described on page 6–42. This is especially if you may need to repair
the Main board. Saving this information means you can simply load this
NVDATA.TXT file into Main board and avoid running the entire Adjustment
Procedure. If you exchange the Main board for another, you must run the full
Adjustment Procedure described on page 5–1.
WFM 601A, WFM 601E, & WFM 601M Service Manual
6–23
Maintenance
NOTE. At times it may be necessary to change a calibration adjustment to
determine if a circuit is operational; however, because making this kind of
adjustment can destroy instrument calibration, you should exercise care. Before
changing an adjustment, note its position so you can return its original setting.
7. Determine the extent of the repair. If the necessary repair is complex, you
may want to contact your local Tektronix field office or representative before
continuing. If the repair is minor, such as replacing a component, see the
parts lists in sections 8 and 10 for replacement information. Procedures for
removing and replacing assemblies are described in this section.
NOTE. Use a 2% RMA flux content solder when making repairs. Cleaning off
rosin residue is not recommended. Cleaning solvents may reactivate the rosin and
spread it under components where it can cause corrosion. The initial rosin
residue is not corrosive.
8. Refer to Table 6–9 on page 6–35 to determine the adjustments necessary
following the replacement or repair of any circuit board
Circuit Board Locations
The instrument electrical circuits consist of circuit boards connected by various
types of cables. All of the circuit boards are designated as assemblies. Each
assembly has an alphanumeric designation (A1 through A9). The assembles are
listed here and at the beginning of the Replaceable Electrical Parts list in this
manual.
Figure 6–21 shows the locations of all circuit board assemblies for the waveform
monitor. Table 6–2 lists the functional names and numbers of the circuit boards.

the Main (A3) circuit board. You can replace the EPROM software with a newer
version through the Serial port on the rear panel. The instructions in this section
describe how to use the Upgrade program to upgrade the software in a
WFM 601A, WFM 601E, or WFM 601M waveform monitor. New software
upgrades are released as kits, which give details of the requirements and results
of the upgrade.
NOTE. Adjustment is required following the software upgrade.
If you load new software, adjustment is necessary. Adjustment is required for the
display mode intensities and Arrowhead and Lightning graticules. For more
details, refer to page 6–46.
The Software Upgrade disk included with this manual contains the upgrade
utility software and the latest version of instrument software at the time of
publication.
NOTE. Check the version of the waveform monitor boot ROM before installing
new software. The boot ROM is the socketed IC U13 on the Main board (A3). See
Figure 6–26. The A3 Main board is the large board on the bottom of the
waveform monitor. Read the last two digits from the part number label on the
boot ROM to determine the version. If the boot ROM version is 00 or 01, you
need to replace it with the 02 boot ROM before loading new software. Contact
your Tektronix Service Representative for more information.

Getting Started
The Upgrade program overwrites the instrument software contained in Flash
EPROM with a newer software version. The Upgrade program can also load
software after replacement of the Flash EPROM.
Determining the Current Software Version. Before performing an upgrade, confirm
that your current version of operating software is older than the upgrade version.
To determine the software version on your waveform monitor follow these steps:
1. Press the CONFIG menu button.
2. Select the CALIBRATE submenu.
3. Find the software version number located in the lower right corner of the
CALIBRATE submenu. It is preceded by the letter V. The coprocessor code,
preceded by the letter C, is not important here.
4. The software version number for the upgrade is printed on the diskette label.
If the version number on the diskette is newer (higher) than the version
number on your waveform monitor, you may benefit from an upgrade.
NOTE. Check the version of the waveform monitor boot ROM before installing
new software. The boot ROM is the socketed IC U13 on the Main board (A3). See
Figure 6–26. The A3 Main board is the large board on the bottom of the
waveform monitor. Read the last two digits from the part number label on the
boot ROM to determine the version. If the boot ROM version is 00 or 01, you
need to replace it with the 02 boot ROM before loading new software. Contact
your Tektronix Service Representative for more information.
Configure the PC. For better file security and execution speed, you should copy
the contents of the 3.5 inch disk to your hard drive and run the program from
there. You also need to configure your PC for remote communications before
running the Upgrade program. You can run the Upgrade program from the floppy
drive on your PC, if necessary. To prepare the PC, follow these steps:
1. Insert the upgrade disk into the 3.5 inch floppy drive on the PC and copy the
contents to a directory on your hard drive.
2. Connect the rear-panel RS-232 connector of the waveform monitor to the
COM 1, 2, 3, or 4 connector on the PC using a cable wired as shown in
Figure 6–25.
3. Set the serial port communication parameters for the PC as shown in

Replacing the Boot ROM
This procedure replaces the boot ROM on the A3 Main board with the new
version. You should replace the boot ROM if you have an older instrument with a
–00 or –01 version of the boot ROM. The main advantage of changing the boot
ROM from –01 to –02 is the ability to configure the waveform monitor to work
in other compatible models. The –00 boot ROM must be changed to be compatible with the software versions 2.0 and above.
To access the boot ROM, you need to remove the cover and turn the instrument
over. The A3 Main board is the large board on the bottom as shown on
page 6–25.
To replace the boot ROM, follow these steps:
1. Remove the instrument from the cabinet as described on page 6–7.

Upgrading the Software
Use the following procedure to upgrade the software on your waveform monitor.
The procedure takes about 35 minutes to complete.
CAUTION. Interrupting the Upgrade program before normal completion will
corrupt the Flash EPROM. To prevent this, ensure that your PC and waveform
monitor are not used or interrupted while the Upgrade program is running. To
recover from an unsuccessful upgrade attempt, see Recovering from an Interrupted or Failed Upgrade on page 6–45. If this recovery procedure is not
successful, return the waveform monitor to Tektronix for repair.
1. Ensure that the file NVDATA.TXT is not located in the same directory as the
Upgrade program files. NVDATA.TXT is a temporary file created by the
Upgrade program to hold user presets and calibration information during the
upgrade. If NVDATA.TXT is present, move it to another directory or rename
it. For more information about NVDATA.TXT, see Using NVDATA.TXT on
page 6–43.
2. Exit from all applications on your PC.
3. From the DOS prompt, change to the directory containing the upgrade files.
4. Type UPGRADE and press ENTER.
5. When asked for the COM port, enter the number of the port you are using. If
you enter an incorrect port number, you are prompted to retry the same port
or quit. You must quit to select a different COM port.

Configuration Procedure
Follow these steps to configure a replacement Main board or to load new
firmware in a repaired Main board.
1. Ensure that the file NVDATA.TXT is not located in the same directory as the
upgrade application files. NVDATA.TXT is a temporary file created by the
Upgrade program to hold user presets and calibration information. If
NVDATA.TXT is present, move it to another directory or rename it. For
more information about NVDATA.TXT, see Using NVDATA.TXT on
page 6–43.
2. Exit from all applications on your PC before running the Upgrade program.
3. From the DOS prompt, change to the directory containing the upgrade files.
4. Type and press ENTER.
5. When asked for the COM port, enter the number of the port you are using. If
you enter an incorrect port number, you are prompted to retry the same port
or quit. You must quit to select a different COM port.

H
Model type, either WFM 601A, WFM 601E, or WFM 601M
H
Instrument serial number from the rear panel, such as B012345
H
Current date in the form MM/DD/YY, such as 03/18/97 for March 18,
1997
7. The program asks whether you want to proceed with the changes. Type to
confirm your entries or to discard your entries.
8. The program checks the current instrument model and compares it against
the model type you entered. The program then stores the new configuration
in NVRAM. The program asks whether to install new software.
H
If the Main board is a replacement from Tektronix, it has the latest
version of software installed. Type to exit the Upgrade program and
proceed to step 10 in this procedure.
H
If you have repaired the EPROM on the Main board, you should proceed
to load new software. Type to load the new version of the software.
9. The program displays status messages as the upgrade progresses. After
approximately 35 minutes, the program displays a message indicating that
the upgrade was successful.

board, reload this information now by following the instructions on
page 6–44.
6–42
WFM 601A, WFM 601E, & WFM 601M Service Manual
Maintenance
11. If you replaced the Main board or were not able to save the calibration
information before repair, perform the procedures in the Adjustment
Procedures section of this manual.
When you load software into the empty EPROM, the program loads default
calibration information into NVRAM. You must perform the full Adjustment
Procedure in order to adjust the default calibration information. This
adjustment will ensure that your waveform monitor meets the advertised
specifications. You can choose to return the waveform monitor to your
Tektronix Service Center for a complete calibration.
12. After repairing or replacing the Main board, verify that the waveform
monitor still performs to specifications by performing the procedures in the
Performance Verification section of this manual.
This completes the configuration procedure.
Using NVDATA.TXT
During the upgrade process, the Upgrade program saves user presets and
calibration information from your waveform monitor NVRAM to a temporary
file named NVDATA.TXT. After the program loads the new software, it
automatically reloads the presets and calibration information from
NVDATA.TXT back into NVRAM. This process configures your waveform
monitor with the operating parameters it had before you ran the Upgrade
program. Before exiting the upgrade, and after ensuring that NVDATA.TXT was
loaded correctly, the program deletes NVDATA.TXT.
If the NVDATA.TXT file is lost, you can recalibrate the waveform monitor by
using the Adjustment Procedures in this manual. Alternatively, if you have saved
a copy of the NVDATA.TXT file, you can load the contents of NVDATA.TXT
into the waveform monitor using the UPGRADE –R option described in
Reloading NVDATA.TXT on page 6–45. Each waveform monitor has unique
calibration information in its NVRAM. Loading the NVDATA.TXT saved from
one instrument into another instrument will result in second instrument being
uncalibrated.
Backing up Calibration Information and Presets. If NVRAM fails, your waveform
monitor can lose calibration information and stored presets. To ensure that you
retain the calibration information, you can copy the NVRAM data into the
NVDATA.TXT file using the following procedure. This procedure takes about
two minutes.
1. Exit from all applications on your PC.
2. From the DOS prompt, change to the directory containing the upgrade files.
3. Type and press ENTER.
WFM 601A, WFM 601E, & WFM 601M Service Manual
6–43
Maintenance
The option saves the current front-panel settings, presets, and calibration
information into the working directory in the file NVDATA.TXT and exits.
4. Rename NVDATA.TXT or move it into another directory to prevent the
Upgrade program from overwriting it.
Calibration information is unique to each waveform monitor. Make a separate
backup of the NVDATA.TXT file for each waveform monitor.
Loading NVDATA.TXT into NVRAM. To load an existing NVDATA.TXT file into
NVRAM, use the following procedure. Loading the data file takes about two
minutes to complete. Loading the NVDATA.TXT saved from one instrument into
another instrument will result in second instrument being uncalibrated.
1. Ensure that the NVDATA.TXT file from your waveform monitor is in the
same directory as the Upgrade program files.
2. Verify the RS-232 configuration as shown in Figure 6–25 on page 6–38 and
Table 6–10, on page 6–38.
3. Exit from all applications on your PC.
4. From the DOS prompt, change to the directory containing the upgrade files.
5. Type and press ENTER.
The option attempts to reload the NVDATA.TXT file, but makes no other
changes to your waveform monitor.
6. When asked for the COM port, enter the number of the port you are using.
The Upgrade program now attempts to restore the information from
NVDATA.TXT to NVRAM.
Recovering from an
Interrupted or Failed
Upgrade
In rare cases, the Upgrade program may quit prematurely; for example, if power
to the PC or the waveform monitor is interrupted, the RS-232 connection is
broken, or the Upgrade program is significantly delayed by another application.
If the Upgrade program quits prematurely, use the following procedure.
1. Save a copy of NVDATA.TXT into another file or location.
Saving a copy now will back up your presets and calibration information.
Leave a copy of NVDATA.TXT in the directory with the upgrade files. You
can use this copy to restore the settings to your waveform monitor.
2. Verify the RS-232 configuration as shown in Figure 6–25 on page 6–38 and

Each assembly in the instrument is assigned an assembly number (for example A5). The
assembly number appears in the title on the diagram, in the lookup table for the schematic
diagram, and corresponding component locator illustration. The Replaceable Electrical
Parts list is arranged by assembly in numerical sequence; the components are listed by
component number.
This section contains the block diagrams, circuit board illustrations, component locator
tables, and schematic diagrams. The block diagrams support the Theory of Operation in
section 3. The block diagrams include references to the schematic diagrams as numbers
within diamond shapes. The referenced schematics shows detail for the circuit blocks.
The circuit board information is organized by circuit board number. The information for
each circuit board follows the pattern: circuit board illustration, component locator table,
and schematic diagram.
Symbols
Graphic symbols and class designation letters are based on ANSI Standard Y32.2-1975.
Abbreviations are based on ANSI Y1.1-1972.
Logic symbology is based on ANSI/IEEE Standard 91-1984 in terms of positive logic.
Logic symbols depict the logic function performed and can differ from the manufacturer’s
data.
The forward slash (/) preceding a signal name indicates that the signal performs its
intended function when in the low state.
Other standards used in the preparation of diagrams by Tektronix, Inc., include the
following:

Component Locator Diagrams
The schematic diagram and circuit board component location illustrations have grids
marked on them. The component lookup tables refer to these grids to help you locate a
component. The circuit board illustration appears only once; its lookup table lists the
diagram number of all diagrams on which the circuitry appears.
Some of the circuit board component location illustrations are expanded and divided into
several parts to make it easier for you to locate small components. To determine which part
of the whole locator diagram you are looking at, refer to the small locator key shown
below. The gray block, within the larger circuit board outline, shows where that part fits in
the whole locator diagram. Each part in the key is labeled with an identifying letter that
appears in the figure titles under component locator diagrams.
