INTRODUCTION
The AVR-GHV1-B is a high performance, GPIB and RS232-equipped instrument
capable of generating 0 to 500V at repetition rates up to 1 kHz into high-impedance
loads of 100 kΩ or higher. The pulse width is variable from 200 ns to 500 ms, and the
duty cycle may be as high as 80%. Rise and fall times are fixed at less than 40 ns. The
AVR-GHV1-B includes an internal trigger source, but it can also be triggered or gated
by an external source. A front-panel pushbutton can also be used to trigger the
instrument. The output pulse width can be set to follow an input trigger pulse width.
The output voltage polarity depends on the model number:
"-P" units: 0 to +500 Volts
"-N" units: 0 to -500 Volts
"-PN" units: 0 to ±500 Volts
The AVR-GHV1-B features front panel keyboard and adjust knob control of the output
pulse parameters along with a four line by 40-character backlit LCD display of the
output amplitude, pulse width, pulse repetition frequency, and delay. The instrument
includes memory to store up to four complete instrument setups. The operator may use
the front panel or the computer interface to store a complete “snapshot” of all key
instrument settings, and recall this setup at a later time.
The instrument is protected against overload conditions (such as short circuits) by an
automatic control circuit. An internal power supply monitor removes the power to the
output stage for five seconds if an average power overload exists. After that time, the
unit operates normally for one second, and if the overload condition persists, the power
is cut again. This cycle repeats until the overload is removed.
This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.

HIGH-VOLTAGE PRECAUTIONS
CAUTION: This instrument provides output voltages as high as 500 Volts under
normal operating conditions, and generates up to 530V internally, so extreme caution
must be employed when using this instrument. The instrument should only be used by
individuals who are thoroughly skilled in high voltage laboratory techniques. The
following precautions should always be observed:
1) Keep exposed high-voltage wiring to an absolute minimum.
2) Wherever possible, use shielded connectors and cabling.
3) Connect and disconnect loads and cables only when the instrument is turned off.
4) Keep in mind that all cables, connectors, oscilloscope probes, and loads must
have an appropriate voltage rating.
Do not attempt any repairs on the instrument, beyond the fuse replacement procedures
described in this manual. Contact Avtech technical support (see page 2 for contact
information) if the instrument requires servicing.

6) HV, MHV or HN output connectors can also be provided. To specify, suffix the model number by -SHV, -MHV or -HN as required.
7) Valid when the load is connected with zero cable length (for instance, on a binding post adapter). The rise and fall times will degrade for non-zero
lengths of cable, due to the product of the 50 Ohm output impedance and the cable capacitance. The maximum cable length for operation (with
degraded rise and fall times) is 2 meters (6 feet). If your application requires longer cable lengths, contact Avtech for appropriate modifications or
applications assistance.

1. POWER Switch. This is the main power switch. When turning the instrument on,
there may be a delay of several seconds before the instrument appears to respond.
2. OVERLOAD Indicator. When the instrument is powered, this indicator is normally
green, indicating normal operation. If this indicator is yellow, an internal automatic
overload protection circuit has been tripped. If the unit is overloaded (by operating at
an exceedingly high duty cycle or by operating into a very low impedance), the
protective circuit will disable the output of the instrument and turn the indicator light
yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after
which the instrument will attempt to re-enable the output (i.e. light green) for about 1
second. If the overload condition persists, the output will be disabled again (i.e. light
yellow) for another 5 seconds. If the overload condition has been removed, the
instrument will resume normal operation.
This overload indicator may flash yellow briefly at start-up. This is not a cause for
concern.
3. OUT CONNECTOR. This N-type connector provides the output to a 100 kΩ (or
higher) load.
Caution: Voltages as high as ±500V may be present on the center conductor of
this output connector. Avoid touching this conductor. Connect to this connector
using standard coaxial cable, to ensure that the center conductor is not exposed.
4. SYNC OUT. This connector supplies a SYNC output that can be used to trigger
other equipment, particularly oscilloscopes. This signal leads (or lags) the main
output by a duration set by the "DELAY" controls and has an approximate amplitude
of +3 Volts to RL > 1kΩ with a pulse width of approximately 100 ns.
5. LIQUID CRYSTAL DISPLAY (LCD). This LCD is used in conjunction with the
keypad to change the instrument settings. Normally, the main menu is displayed,
which lists the key adjustable parameters and their current values. The

“Programming Manual for -B Instruments” describes the menus and submenus in
detail.

provided on the back panel for AC power connection to the instrument. One end of
the detachable power cord that is supplied with the instrument plugs into this socket.
2. AC FUSE DRAWER. The two fuses that protect the AC input are located in this
drawer. Please see the “FUSES” section of this manual for more information.
3. DC FUSES. These two fuses protect the internal DC power supplies. Please see the
“FUSES” sections of this manual for more information.
4. GATE. This TTL-level (0 and +5V) logic input can be used to gate the triggering of
the instrument. This input can be either active high or active low, depending on the
front panel settings or programming commands. (The instrument triggers normally
when this input is unconnected). When set to active high mode, this input is pulleddown to ground by a 1 kΩ resistor. When set to active low mode, this input is pulledup to +5V by a 1 kΩ resistor.
5. TRIG. This TTL-level (0 and +5V) logic input can be used to trigger the instrument, if
the instrument is set to triggering externally. The instrument triggers on the rising
edge of this input. The input impedance of this input is 1 kΩ. (Depending on the
length of cable attached to this input, and the source driving it, it may be desirable to
add a coaxial 50 Ohm terminator to this input to provide a proper transmission line
termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thru 50
Ohm terminator is suggested for this purpose.)
When triggering externally, the instrument can be set such that the output pulse
width tracks the pulse width on this input, or the output pulse width can be set
independently.
19
6. GPIB Connector. A standard GPIB cable can be attached to this connector to allow
the instrument to be computer-controlled. See the “Programming Manual for -B
Instruments” for more details on GPIB control.
7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be
attached to this connector to allow the instrument to be computer-controlled. See the
“Programming Manual for -B Instruments” for more details on RS-232 control.
8. LAN Connector and Indicator. (Optional feature. Present on -TNT units only.) The
-TNT option "Internet-enables" Avtech pulse generators by adding this standard
Ethernet port to the rear panel, in addition to the IEEE-488.2 GPIB and RS-232 ports
normally found on "-B" units. Commands are sent using the standard Telnet protocol.
The SCPI-compliant command set is the same as that used for GPIB and RS-232
control. The -TNT option uses the Dynamic Host Configuration Protocol (DHCP) to
obtain its network address. A DHCP server must be present on the local network for
the -TNT option to operate properly.
9. AMP Connector. This connector, if present, is not used.

GENERAL INFORMATION
BASIC PULSE CONTROL
This instrument can be triggered by its own internal clock or by an external TTL trigger
signal. In either case, two output channels respond to the trigger: OUT and SYNC. The
OUT channel is the signal that is applied to the load. Its amplitude and pulse width are
variable. The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger
oscilloscopes or other measurement systems. When the delay is set to a positive value
the SYNC pulse precedes the OUT pulse. When the delay is set to a negative value the
SYNC pulse follows the OUT pulse.
These pulses are illustrated below, assuming internal triggering and a positive delay:

TRIGGER MODES
This instrument has four trigger modes:
•
Internal Trigger: the instrument controls the trigger frequency, and generates the
clock internally.
•
External Trigger: the instrument is triggered by an external TTL-level clock on the
back-panel TRIG connector.
•
Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE”
pushbutton.
•
Hold Trigger: the instrument is set to not trigger at all.
These modes can be selected using the front panel trigger menu, or by using the
appropriate programming commands. (See the “Programming Manual for -B
Instruments” for more details.)
PULSE WIDTH MODES
This instrument has two pulse width modes:
•
Normal: the instrument controls the output pulse width.
•
PW IN=PW OUT: the output pulse width equals the pulse width of the trigger signal on
the “TRIG” connector. The instrument must be in the external trigger mode.
These modes can be selected using the front panel pulse width menu, or by using the
appropriate programming commands. (See the “Programming Manual for -B
Instruments” for more details.)
GATING MODES
Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector.
The instrument can be set to stop triggering when this input high or low, using the frontpanel gate menu or the appropriate programming commands. This input can also be
set to act synchronously or asynchronously. When set to asynchronous mode, the
GATE will disable the output immediately. Output pulses may be truncated. When set
to synchronous mode, the output will complete the full pulse width if the output is high,
and then stop triggering. No pulses are truncated in this mode.
23
OUTPUT IMPEDANCE
The AVR-GHV1-B has an output impedance (i.e., an internal resistance in series with
the output) of 50 Ohms, to provide transmission line back-matching and short-circuit
protection.
The rise and fall times are fixed at less than 40 ns. However, since the output
impedance is 50Ω, the rise and fall times will degrade if cable lengths longer than 1
meter (3 feet) are used on the output, due to the cable capacitance. The maximum
usable cable length is 2 meters (6 feet).
LOAD IMPEDANCE
The AVR-GHV1-B can drive load impedances of 100 kΩ or higher. It is NOT designed
to drive 50 Ω loads or highly capacitive loads. (The AVR-GHV1-B is tested with
capacitive loads of 330 pF. Load capacitance should not exceed 330 pF.)
BURST GENERATION (-BR OPTION)
The waveforms given above assume that a single output pulse is generated for each
trigger event (regardless of the source). However, when the burst mode feature is used
on units with the -BR option, the instrument can generate 1-500 pulses for each
individual trigger event. The number of output pulses in each burst can be adjusted
from 1 to 500 using the front-panel controls (using the “N” menu), or by a computer
command. The time between pulses (i.e., from the falling edge of one pulse to the
rising edge of the next pulse) can also varied from 1 ms to 1.0 seconds from the front
panel (using the “BUR” menu), or by computer command.

SEPARATION
The burst mode may also be used with the front-panel “Single Pulse” pushbutton as a
trigger source. (Pressing the pushbutton will actually generate a single burst, rather
than a single pulse, in this mode.) Computer commands can also trigger a burst.
To control the burst count and timing from the front-panel, use the “N” and “BUR”
menus. To control them using computer commands, use the SOURce:PULSe:COUNt
and SOURce:PULSe:SEParation commands, as described in the programming manual.
The pulse spacing is constrained by several factors:
1. The maximum PRF limitation of the instrument applies within the burst. That is,
timing between two consecutive leading edges must lie between a minimum of
1/PRFMAX and a maximum of 1.0 seconds, where PRFMAX is the maximum
pulse repetition frequency specification for the instrument.
For this instrument, the maximum PRF for the instrument is 1 kHz, so the time
between two leading edges within the burst may not be smaller than 1
millisecond. The total number of pulses per second (i.e., Trigger Frequency x
Burst Count) must also be less than 1 kHz.
2. The maximum duty cycle limitation of the instrument can not be exceeded inside
the burst. Within the burst, the duty cycle may be calculated using DCBURST =
100% x Pulse Width / (Pulse Width + Pulse Separation). The total average duty
cycle is equal to DCAVG = 100% x Pulse Width x Burst Count x Trigger
Frequency. Both DCBURST and DCAVG must be less than the rated maximum
duty cycle of the instrument.
For this instrument, the maximum duty cycle is 80%.
25
PREVENTING OUTPUT STAGE FAILURE
The output stage is protected against overload conditions by an overload circuit and
fuses on the main frame back panel. However, the output switching elements may fail if
the unit is triggered at a PRF exceeding 1 kHz or if the load impedance is too low (<
100 kΩ or > 330 pF). Heating and subsequent possible failure of the output stage is
reduced if the following action is taken where possible:
•
PRF is kept to a minimum, i.e. operate in a low PRF range when possible rather
than in a high PRF range.
•
Keep the output PW to a minimum.
•
Never apply an externally generated voltage to the output port.
•
Reduce the amplitude below 100 Volts before changing the output polarity. Note
that internal protection circuits will prevent the polarity from switching when the
amplitude is set higher than ±100V, until the internal power supplies have
discharged the voltage on the internal energy-storage capacitors to below ±100V.
This may take several seconds.
•
Use the correct load impedance (> 100 kΩ and < 330 pF).
•
Keep output cable lengths to 2 meters (6 feet) or less.
26
OPERATIONAL CHECK
This section describes a sequence to confirm the basic operation of the instrument. It
should be performed after receiving the instrument. It is a useful learning exercise as
well.
Before proceeding with this procedure, finish read this instruction manual thoroughly.
Then read the “Local Control” section of the “Programming Manual for -B Instruments”
thoroughly. The “Local Control” section describes the front panel controls used in this
operational check - in particular, the MOVE, CHANGE, and ADJUST controls.

1. Connect a cable from the SYNC OUT connector to the TRIG input of an
oscilloscope. Connect a 100 kΩ (or higher) load to the OUT connector and place
the scope probe across this load. The load resistor must have a voltage rating of at
least 500V. The power dissipated in the resistor is given by
P = (V2 / R) × (PW / T) = (V2 / R) × PW × f
where “V” is the output voltage, “R” is the load resistance, “PW” is the pulse width,
and “T” is the pulse period (1/frequency), and “f” is the frequency. If a 100 kΩ
resistor is used, the worst-case power dissipation is 2.5 Watts. (Ohmite “OY”
ceramic composition resistors - http://www.ohmite.com - are recommended for such
applications. These resistors are readily available from http://www.digi-key.com/
and other distributors.)
2. Set the oscilloscope to trigger externally with the vertical setting at 100 Volts/div
and the horizontal setting at 1 us/div. Be sure that your oscilloscope and probe
setup can handle the maximum amplitude of 500V. A high-voltage attenuator might
be necessary to avoid damaging the probe and oscilloscope.
27
3. Turn on the AVR-GHV1-B. The main menu will appear on the LCD.
4. To set the AVR-GHV1-B to trigger from the internal clock at a PRF of 1 kHz:
The arrow pointer should be pointing at the frequency menu item. If it is not, press
the MOVE button until it is.
Press the CHANGE button. The frequency submenu will appear. Rotate the
ADJUST knob until the frequency is set at 1 kHz.
The arrow pointer should be pointing at the “Internal” choice. If it is not, press
MOVE until it is.
Press CHANGE to return to the main menu.
5. To set the delay to 1 us:
Press the MOVE button until the arrow pointer is pointing at the delay menu item.
Press the CHANGE button. The delay submenu will appear. Rotate the ADJUST
knob until the delay is set at 1 us.
The arrow pointer should be pointing at the “Normal” choice. If it is not, press
MOVE until it is.
Press CHANGE to return to the main menu.
6. To set the pulse width to 1 us:
Press the MOVE button until the arrow pointer is pointing at the pulse width menu
item.
Press the CHANGE button. The pulse width submenu will appear. Rotate the
ADJUST knob until the pulse width is set at 1 us.
The arrow pointer should be pointing at the “Normal” choice. If it is not, press
MOVE until it is.
Press CHANGE to return to the main menu.
7. At this point, nothing should appear on the oscilloscope.
8. To enable the output:
Press the MOVE button until the arrow pointer is pointing at the output menu item.
Press the CHANGE button. The output submenu will appear.
28
Press MOVE until the arrow pointer is pointing at the “ON” choice.
Press CHANGE to return to the main menu.
9. To change the output amplitude:
Press the MOVE button until the arrow pointer is pointing at the amplitude menu
item.
Press the CHANGE button. The amplitude submenu will appear. Rotate the
ADJUST knob until the amplitude is set at +200V (or -200V for "-N" instruments).
Observe the oscilloscope. You should see 1 us wide, 200V pulses.
Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should vary.
Reduce the amplitude to 50V (or -50V for "-N" instruments), using the adjust knob.
For "-PN" units only: Change the output polarity by pressing the “+/-” button. The
output amplitude should become negative, and you should see -50V pulses on
the oscilloscope. (Avoid switching polarity when the amplitude is higher than
100V. Reduce the amplitude first.)
Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should vary.
Press CHANGE to return to the main menu.
10. Repeat step 9, but set the amplitude to zero.
11. This completes the operational check.

PROGRAMMING YOUR PULSE GENERATOR
KEY PROGRAMMING COMMANDS
The “Programming Manual for -B Instruments” describes in detail how to connect the
pulse generator to your computer, and the programming commands themselves. A
large number of commands are available; however, normally you will only need a few of
these. Here is a basic sample sequence of commands that might be sent to the
instrument after power-up:
*rst
trigger:source internal
frequency 1000 Hz
pulse:width 1 us
pulse:delay 2 us
volt 200
output on
(resets the instrument)
(selects internal triggering)
(sets the frequency to 1000 Hz)
(sets the pulse width to 1 us)
(sets the delay to 2 us)
(sets the amplitude to 200 V)
(turns on the output)
For triggering a single event, this sequence would be more appropriate:
*rst
trigger:source hold
pulse:width 1 us
pulse:delay 2 us
output on
volt 200
trigger:source immediate
trigger:source hold
output off
(resets the instrument)
(turns off all triggering)
(sets the pulse width to 1 us)
(sets the delay to 2 us)
(turns on the output)
(sets the amplitude to 200 V)
(generates a single non-repetitive trigger event)
(turns off all triggering)
(turns off the output)
To set the instrument to trigger from an external TTL signal applied to the rear-panel
TRIG connector, use:
*rst
trigger:source external
pulse:width 1 us
pulse:delay 2 us
volt 200
output on
(resets the instrument)
(selects internal triggering)
(sets the pulse width to 1 us)
(sets the delay to 2 us)
(sets the amplitude to 200 V)
(turns on the output)
These commands will satisfy 90% of your programming needs.

MECHANICAL INFORMATION
TOP COVER REMOVAL
If necessary, the interior of the instrument may be accessed by removing the four
Phillips screws on the top panel. With the four screws removed, the top cover may be
slid back (and off).
Always disconnect the power cord and allow the instrument to sit unpowered for 10
minutes before opening the instrument. This will allow any internal stored charge to
discharge.
There are no user-adjustable internal circuits. For repairs other than fuse replacement,
please contact Avtech ([email protected]) to arrange for the instrument to be
returned to the factory for repair. Service is to be performed solely by qualified service
personnel.
Caution: High voltages are present inside the instrument during normal operation.
Do not operate the instrument with the cover removed.
RACK MOUNTING
A rack mounting kit is available. The -R5 rack mount kit may be installed after first
removing the one Phillips screw on the side panel adjacent to the front handle.
ELECTROMAGNETIC INTERFERENCE
To prevent electromagnetic interference with other equipment, all used outputs should
be connected to shielded loads using shielded coaxial cables. Unused outputs should
be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to
prevent unintentional electromagnetic radiation. All cords and cables should be less
than 3m in length.
33
MAINTENANCE
REGULAR MAINTENANCE
This instrument does not require any regular maintenance.
On occasion, one or more of the four rear-panel fuses may require replacement. All
fuses can be accessed from the rear panel. See the “FUSES” section for details.
CLEANING
If desired, the interior of the instrument may be cleaned using compressed air to
dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for
instructions on accessing the interior.) No other cleaning is recommended.
