2- THEORY of OPERATION
Vectra™ Pro
2.1 Overview
The Vectra series electrotherapy products are comprised of several PC board assemblies housed within a common
enclosure. These assemblies each support a distinct function in the product. The basic elements are User Interface,
Control Board, Stim Generation Board, Ultrasound Board, Ultrasound Applicator, and Power Supply Circuits.
See Figure 2.1 below.
FIGURE 2.1
2.2 Power Supply Circuits
A universal input power supply provides all parts of the system with 12 volts DC. The supply is connected to the mains
at all times when the cord is attached. The power switches on the top of the unit, switch the 12V output of the power
supply to the different components in the system by way of the Power Distribution Board. The 12V supply is regulated
locally at each PC board as required.
2.3 Control Board
The Control Board serves just as its name implies. It controls the operation of the stim boards, ultrasound boards, user
interface, and accessories. The control board communicates to the stim boards and ultrasound board through a
proprietary 8-bit parallel bus. The control board drives the display. The control board reads the touch screen or menu
buttons. The control board also reads the amplitude and contrast controls. The control board manages the ZIP drive and
infrared printer port. The control board through the power supply distribution board operates the gel warmer. Sound
output is generated by the control board and routed to an internal speaker or alternately to external speakers. The
control board reads the patient switch or manual stim switch.
3
2- THEORY of OPERATION
Vectra™ Pro
2.4 Stim Generation Board
The stim board creates all muscle stimulation output. Communications to the stim board is via an 8-bit data bus
and a dual-port RAM. A processor on the stim board acts on messages passed to it by the control board to set up
waveforms and adjust output amplitude. Information can likewise be passed from the stim board back to the control
board for monitoring current, GSR mode levels, etc. If the stim board does not respond as expected to a command
from the control board, output is stopped and an error message is generated.
2.5 Ultrasound Board and Applicator
The ultrasound board generates the 1 or 3.3 MHz output to drive the ultrasound applicator. The ultrasound board
is accessed much like an I/O port by the control board. It can provide current and voltage information about the
ultrasound output of the board. The calibration data for the applicator is passed through the ultrasound board from
the applicator up to the control board. By storing the calibration data in the applicator there is no calibration
necessary for the ultrasound board and any calibrated Chattanooga Group, Inc. compatible applicator can be
attached and operated to provide accurate output.
2.6 User Interface and Accessories
The LCD or EL display panel provides the operator visible feedback in the way of menu choices. Pressing the
touchscreen or menu buttons makes selections from the menus. The control board interprets these user inputs and
responds accordingly. Audible feedback is given as well for events such as keypresses and end of treatment.
The control board accesses the ZIP drive via an IDE interface. Treatment presets can be exported and imported
using the disks, as well as giving patients pre-treatment information or the user in-service instruction. The 5 volts
necessary to operate the drive is generated on the power supply distribution board.
The infrared printer port works exclusively with the Jeteye infrared to printer interface unit. This allows printing
treatment information to any type of printer the user might have. Due to the large number of printers available,
direct printing to infrared-capable printers is not supported.

methods used at the factory before shipment of
any Vectra Pro unit.
2. Due to the complex nature of the
technology utilized by Chattanooga Group,
Inc., the recommended troubleshooting
techniques are to determine “Bad Board”
and board replacement only. No board
component level troubleshooting is
recommended nor will information or parts
be supplied by Chattanooga Group, Inc. Any
board component level troubleshooting
performed will be at sole risk and liability of
the Service Technician performing such
troubleshooting techniques.
3. Once a particular PC Board has been determined
as bad, use the Schematics provided in this
section to isolate and confirm “Bad Board” before
arbitrary replacement of the suspected board.
4. Stimulator Board(s);
a) Stim Board #1 controls Channels 1 & 2.
b) Stim Board #2 controls Channels 3 & 4.
B. Special Tools, Fixtures & Materials Required
1. Certain tests require the use of special Tools
and/or Fixtures. These will be listed at the
particular test where they are required. Testing
with any other special tool or fixture other than
those stated could give erroneous readings or
test results. Always perform the tests exactly as
stated to ensure accurate results.
2. Any special tools or fixtures required can be
obtained through Chattanooga Group, Inc.,
Service Department.
3. Scope and other standard test equipment
settings will be listed for each test performed to
aid in performing the test to OEM standards and
ensure proper readings.
4. The troubleshooting and repair of the Vectra Pro
units, should be performed only by authorized
technicians trained and certified by Chattanooga
Group, Inc.
C. Equipment Required
1. Oscilloscope and Probes
2. 650 Ohm load for outputs
3. 10k Load for output
4. Digital Multimeter
10. Ohmic Instruments UPM DT 10 Ultrasound
Power Meter.
11. Degassed Water (<5ppm) for Ultrasound
Power Meter.
a) Recipe(s) for Degassed Water
1) Boil Distilled Water for 30 minutes. Place
water in a nonporous container and
immediately cover with cellophane.
Allow to cool to room temperature of
approximately 70°F (21°C). May be
refrigerated to aid cooling time.
2) Bring Distilled Water to a boil. Place the
container under vacuum for 5 to 10 minutes.
12. Dissolved Oxygen Test Kit. Used to test oxygen
level of degassed water.
NOTE:
Two liter softdrink bottles are ideal storage and transport
containers for degassed water as they are designed to
keep oxygen out. Do not allow aeration of degassed water
during transport or filling of the power meter.
Do not use Tap Water or Distilled water in the Ultrasound
Power Meter. Use only Degassed Water in order to obtain
correct test results. The chart below illustrates the oxygen

5.31 Ultrasound Board Amplifier Circuit Tests
A. Pulse Output Generation Test
1. Set Scope;
a) Time- 500ns, Channel- 2.0V, Trigger- DC
b) Reference Scope to DC Ground.
2. Check pins 5 and 7 of U15 (see “A” on schematic) for
presence of square wave. See Figure 5.41.
NOTE:
Perform step 2 at 1MHz and 3.3MHz settings @ 100% Duty
Cycle.
3. Absence of square wave at any or all of the check
points in step 2 indicate bad Ultrasound Board.
Replace with Part Number 79291D.
B. Head Detect Voltage Test
Perform this test with all available Ultrasound Applicators
available for the unit being tested (2cm2, 5cm2, 10cm2). This will
aid in isolating bad board or bad Ultrasound Applicator.
1. Plug in the Ultrasound Applicator.
2. Using a Digital Multimeter, check the voltage at #1 and
#2 of L13. See “B” on schematic. See Figure 5.42 for
voltage specifications.
3. Repeat steps 1 and 2 with all other available
Ultrasound Applicators for unit being tested.
4. If multimeter reads 5VDC, plug in a known good
Ultrasound Applicator and re-test. If voltage is in spec
per Figure 5.42, then Applicator is bad. If voltage reads
5VDC with known good Applicator, then Ultrasound
Board is bad. Replace board with Part Number
79291D.
NOTE:
See Section 6 for Removal & Replacement procedures.
