INSTALLATION
Unpacking Information
equipment, checking for iii-transit damage at the same time.
‘ Should any damage he noted, notify the freight carrier at once to
ﬁle a freight claim. Do not discard any packing material until told
-’ to do so by the can'ier. Also, notify Communication Microwave
Corp (COMWAVE) of any damages or of missing materials from
the shipment.
” While unpacking, carefully compare the packing list with the
Retain original boxes and internal packing materials to adequately protect equipment to
be returned to the factory for repairs, upgrades, or modifications.
Physical Installation
COMWAVE transmitters have been designed to accept standard 19-inch rackmounts
with slide rails. Slide rails enable easy access to internal adjustable controls and other
maintenance/adjustments. In most cases, COMWAVE provides a system equipment rack
layout diagram that will assist in the proper installation and orientation of equipment.
The transmitter system requires 8.75” of vertical rack space (including a modulator)
Generally, all equipment is mounted in close proximity in the same rack for the
convenience of cabling. Mount the slide rails into the rack with the hardware supplied.
Use tapered screws for mounting the front brackets (tapered screws allow the drawer to
be fully seated).
Pull slide rails outward until they lock into place. Carefully align drawer with slide rails
and mate. Unlock slide rails by depressing the lock button on each rail while pushing
drawer inward. Drawer should slide easily into rack. If binding occurs, rail mounting
brackets are in need of adjustment. Loosen brackets and manipulate drawer to seat rails
to match receiver drawer. Tighten brackets once free sliding motion has been achieved.
System Grounding
For proper system operation, it is imperative that the system be adequately grounded,
Each individual equipment rack requires grounding to the main building ground When
bolting ground wires to racks. sand ﬁnish to remove paint ensuring a good bond.

Q GOMWAVE Installation
Environmental Considerations
The equipment can be safely operated in ambient temperatures of -30 to +50 degrees
Celsius (-22 to +122 degrees Fahrenheit). However, moderate temperatures generally
extend equipment life. Although the equipment may be operated with relative humidity
of up to 95%, the equipment must be protected from conditions which cause
condensation within the equipment.
If a rear door is used to secure the rack cabinet, forced ventilation through the cabinet is
required (600 cfm minimum per transmitter is recommended). An air or temperature
interlock should be incorporated for protection against interruption of ventilation. The
area should be kept dry and clean,
There should be sufficient space in front of the receiver cabinet for the serviceman and
test equipment, plus the full extension of the racked 22" deep chassis. A minimum of 36”
behind the cabinet should be free for rear cabinet access and air movement. Also, ample
room must be available at the cabinet rear for cable placement
Safety Considerations
This equipment utilizes a grounding plug on all power cords. For
personal safety, do not defeat this feature. As with all similar types
of equipment, high voltage can be accessed when the chassis cover
is removed. Special care should be given in areas of fuses, line
switches, and power supplies.
Modern high power solid state equipment contains low output voltage power supplies
with very high current capability, To prevent severe burns, avoid contact of rings,
watches etc, with these circuits. When servicing the transmission line and antenna. care
must be taken to avoid exposure to high-energy microwave.

Q COMAVE Ill MHz Reference Input to the Transmitter
A Theme-n n,
10 MHz REFERENCE IN
An externally applied 10 MHZ reference signal is needed to determine the stability of an
individual transmitter PLL synthesizer. This signal can originate from an optional 10
MHZ Reference Drawer, Loran C. GPS receiver, or from another transmitter which
contains a 10 MHZ reference oscillator intemally. An intemal 10 MHz reference can
drive up to three additional transmitters. Use RGS9/U 75-ohm cable.
Reference Signals
Two methods are available to apply 10 MHZ reference signals to phase lock a transmitter
system. An internal reference card is used to lock up to four transmitters. When more
than four transmitters are to be locked to the same reference, an external reference drawer
is required. The reference signal level should be +10 dBm +5 dB/-10dB.
lntemal Phaselocking of Transmitters: (Option Kit)
In a one to four channel co-located transmitter system, one transmitter, usually the lowest
channel unit, will contain a precision 10 MHZ reference oscillator module assembly. A
three way signal splitter with cables is provided to distribute the reference signal to the
remaining three units. Should this Qn'mgy transmitter be taken off line, the reference
oscillator assembly must be removed and placed into another transmitter of this type. All
transmitters have the provision to accept this reference oscillator assembly.
External Phaselocking of Transmitters: (Standard Conﬁguration)
When more than four transmitters are co-located, the 10 MHZ reference normally located
inside the lowest transmitter channel of the group is removed and an external 10 MHz
reference drawer along with a 10 MHZ cable kit are used. This drawer contains a
precision 10 MHZ reference oscillator and distribution system. Options are available for
redundancy and/or tighter tolerances including an option that will lock to the global
positioning satellite system. See attached document for cabling details.
NOTE: The 10 MHZ output signals are ofa high level (+17 dBm) and should NOT be
directly cabled to any transmitter/modulator, These signals must ﬁrst be routed through
splitters to reduce the signals to acceptable levels. Located in the 10 MHZ cable kit are
four 8-Way CATV splitters with cable and appropriate connectors. When connected to
any rear panel 10 MHZ jack of the reference drawer, each output of the 8-way splitter
may be connected directly to any transmitter 10 MHZ input. The 8-way splitter has -10
dB typical loss.

A Thomclst Compxnx ___—
TURN ON PROCEDURE
This section covers initial unit tum-on and explains normal operation of the transmitter.
Prior to any initial equipment tum-on, verify that all appropriate wiring interconnections
have been accomplished, see following pages.
Initial Turn-On
1. Ensure the rear mounted main power ON/OFF switch is in the OFF position.
2. Position the front panel rotary function switch to STANDBY,
3. Insert the power plug into a power outlet.
4 Position the main power switch to ON.
*Fan noise should be heard.
5. The following GREEN LED‘s continuously illuminate verifying successful turn
ON.
*IN SIGNAL (if an input signal is applied; requires modulator operation)
*1NTERLOCK
Normal Operation
Rotating the function switch from STANDBY to any other position enables operation.
At that time. the following GREEN LED‘s continuously illuminate conﬁrming normal
operation.
*IN SIGNAL (must have an input signal applied to transmit; requires
modulator operation)
*INTERLOCK
*TRANSMIT
Absence of a green LED indicates a missing signal or parameter. Continuous
illumination of any red status LED indicates a failure has been detected by the diagnostic
circuitry. Refer to the troubleshooting section for failures.
To verify other transmitter parameters using the front panel meter, rotate the function
switch. +11 V PS and FWD PWR should have meter readings of100%. REFL PWR is a
function of the combiners, transmission line, and antenna. Reﬂected power readings less
than 10"/o are typical.

TROUBLESHOOTING
FAILURE MODE DISPLAYS
Comwave transmitters employ comprehensive diagnostic circuitry that monitors the status
of power ampliﬁer modules and critical circuits. Failures can be readily interpreted by
observing the front panel LED diagnostic display and/or monitoring the analog panel meter.
By observing the diagnostic display and metering, the complete transmitter, operational
status is known. Due to the internal transmitter design Comwave does not recommend the
repair of these modules on site. Contact Comwave customer support should a failure occur.
This section explains the various failure mode displays that may be encountered and
possible solutions.
The following status-monitoring LED’s continuously illuminate GREEN during normal
operation. Absence of an LED indicates a missing signal or parameter, which results in a
controlled automatic transmitter shut down.
I'N SIGNAL: Missing video input signal from modulator.
Causest
- Defective cabling to modulator baseband VIDEO INPUT
- Defective/disconnected interlock hamess from modulator to transmitter
- Modulator failure
- Missing baseband source signal to the modulator
Remedy:
- Check cabling
- Check harness between the modulator and transmitter
- Verify video source signal
- Replace modulator
- Measure voltages at 25 pin Diagnostic Interface 12

DIAGNOSTIC INTERFACE
To assist in troubleshooting, COMWAVE transmitters employ a 25-pin computer type
diagnostic interface connector located at the rear of the chassis. This connector is identiﬁed
as J2. Critical power supply, module, and motherboard voltage test points can be
accessed/monitored at this connector. Should a failure occur, the combination of meter
readings, diagnostic LED status lights, and the diagnostic interface voltage test points help
identify the failure.
Attached you will ﬁnd an example diagnostic interface High/Low Window data sheet. This
identiﬁes each interface pin, the associated internal test point, nominal value, and the
expected voltage range.
ANALOG METERING
The front panel analog meter provides a visual indication of the +1] VDC switching power
supply, reﬂected power, or forward power. The +11 VDC switching power supply and
forward power should indicate 100%, Reﬂected power meter readings less than 10% are
typical. By observing the meter readings, transmitter performance can be interpreted.
Analog meter readings in conjunction with the front panel Diagnostic status LED’s help to
identify/isolate failure(s). The following information is provided to assist in troubleshooting
analog meter anomalies.

EQUIPMENT FUSING AND PROTECTION
Fuses: Five replaceable fuses are found in this chassis. The ﬁise locations and values are as
follows:
Location Name Value
Mother Board F1 15 amperes
Mother Board F2 25 amperes
Mother Board F3 25 amperes
Rear Panel AC Input 12 amperes @ 117 VAC or 7 amperes (a) 230 VAC
Power Supply F1 15 amperes @ 117 VAC or 8 amperes (a) 230 VAC
FIGURE 18—0007-1
Surge Suppression: COMWAVE transmitters employ a metal oxide varistor (MOV) voltage
suppressor across the AC line input for protection from moderate power surges. The surge
suppressor value is dependent upon the AC line input voltage. 117 VAC employs a 150 VAC
MOV and 230 VAC uses a 275 VAC MOV.
Thermal Protection: Thermal protection is accomplished using thermostats that close when the
internal temperature exceeds +140 degrees Fahrenheit (+ 60 degrees Celsius). When thermal
shut down occurs, a logic control board removes power from the ﬁnals until the unit is
sufﬁciently cooled.
Interlocks: Interlocks are designed for transistor bias protection for both the FET gate and drain
power supply voltages. See the logic control PC assembly description, Document # DOC13-
0016.

INSPECTIONS AND CLEANING
COMWAVE products have been carefully designed to be maintenance free. Only
periodic inspection and cleaning is necessary
Inspections:
1, Inspect heat sinks monthly for heavy accumulations of dirt and/or insects. Heavy
accumulation of foreign debris impedes cooling effectiveness and could lead to
premature failure,
2 Should any debris be found, shut down the transmitter and unplug the AC line cordi
Remove the top cover and remove any accumulation of foreign debris.
3. After performing routine maintenance be sure to check the tightness of all cable
connections and especially the integrity of RG-SS/U crimp type connectors.
Cleaning:
Clean face plate and outside cover using a damp non-abrasive cloth with a mixture of a
mild detergent and water.

CALIBRATION DESCRIPTION
Front panel meter Ml provides an analog indication of the +11 VDC power supply, reﬂected
power, aural power. or peak visual power. The 2 VDC full-scale meter is calibrated to indicate
100% at 1.4 VDC. Rotary function switch 81 selects the parameter to be monitored
+ll VDC Power Supply: Meter reads 100% during normal operation. Voltage from the
switching power supply is sampled from the motherboard using resistor R43 and calibration
potentiometer V'Rl.
Reﬂected Power: Meter indicates relative reﬂected power. A directional coupler on the output
samples reﬂected power from a -20 dB port, This sample is reduced by a 3 dB attenuator and is
envelope detected by D2 and R6/C2. Reﬂected metering is calibrated by adjusting mother-
board potentiometer VR}.
FWD Power: Meter indicates relative peak visual output power. A directional coupler on the
output samples forward power from a -20 dB port. This sample is reduced by a 3 dB isolation
attenuator and is envelope detected by D1 and IU/Cl in the detector module assembly. A DC
voltage proportional to the carrier power is sent to motherboard U2C. U2C is a buffer ampliﬁer,
which drives D] and C1/R8 to the peak signal value. UZD/U 1C then buffer this voltage to
meter calibration motherboard potentiometer VR4.

DRAWER — INTERNAL THEORY OF OPERATION
The SBOZOD-l receives an Intermediate Frequency (IF) AM modulated visual and FM
modulated aural carrier which is convened to S-band frequency. These microwave carriers are
sent through a common ampliﬁer chain to produce an RF output signal. The transmitter
provides a visual output of 20 watts peak sync and a 15 dB ratio or visual to aural power. An
RF signal path block diagram follows, document # DOC15-0008,
The visual (-8dBm) and aural (-23 dBm) IF carriers are combined internally by the transmitter,
(It is also capable of accepting an extemally combined signal, depending upon the needs of the
system). The IF input signal is cabled to an IF Processor where preconection is introduced to
reduce most linear distortions of the ﬁnal ampliﬁer. The IF Processor also contains an
Automatic Level Control (ALC) circuit for maintaining 100% output power over a iZdB IF
input range. Both precorrection and ALC can be turned off by individual switch controls
located on the module exterior.
The IF Processor output is applied to a driver module where the IF signal is converted with a
microwave local oscillator, A bandpass ﬁlter follows the mixer to prevent out—of-band products
from being ampliﬁed and transmitted The signal then goes back to the driver, where it is
ampliﬁed.
The Final Ampliﬁer is a broad band, fixed gain linear ampliﬁer that does not require any timing.
A -20 dB directional coupler follows providing forward and reﬂected power samples to an
envelope detector. The envelope detector sends the detected samples to the motherboard for
metering. The Notch Filter is the last module the signal passes through before exiting the
transmitter, here, the signal is corrected for inter-modulation distortions. 43 dBm peak visual and
+ 28 dBm aural power are available at the RF output.

A Thoma.“ CnmEnx
IF PROCESSOR
The preconector module contains linearity correction circuitry and an automatic level control
(ALC). Linearity correction circuitry pre-corrects for non—linearities developed in the solid
state power ampliﬁers. The ALC maintains lOO% output power over a 1 2 dB IF input range.
An IF signal is applied to J 1 with a precorrected ALC regulated output signal appearing at J 3.
The IF input signal is attenuated by a variable pin diode attenuator circuit. Depending upon
the amount of forward bias, pin diodes act as variable resistors to the RF signal.
Following input attenuation, a two port passive combiner receives the IF signal. The
combiner is typically used in systems when an auxiliary IF carrier signal is required. The
aimiliary carrier is combined to the IF signal and is ampliﬁed in common service.
The IF signal is sent through two stages of ampliﬁcation and is applied to temperature
compensated linearity correction circuitry. The signal is applied to three linearity correction
circuits each correcting for a separate part of the signal. With switch Si ON, a voltage is
applied to each circuit forward biasing schottky diodes, enabling compensation. When the
switch is OFF, a voltage is applied reverse biasing the diodes, disabling compensation.
Compensation of each circuit is adjustable by potentiometers. These adjustments control the
amount of forward bias through the compensating diodes.
A band switching circuit is employed when used with an agile transmitter. This circuit selects
the biasing network to a pin diode. A control signal is received that enables a relay to select
between two levels of compensation. This allows improved compensation at the band
extremes.
The signal is sent to a final pin
diode circuit where a reference
signal determines the RF output
attenuation/level control. Switch,
52, selects between automatic
ALC or a predetermined manual
reference level. A manual
reference is determined by varying
the output from an 8 VDC
regulator. The ALC circuitry
compares a voltage proportional to
average output power with a
predeﬁned reference and adjusts ,
the variable pin diode attenuator to FIGURE 13-0034-1

MIXER/DRIVER AMPLIFIER
This module consists of three compartments: a Mixer, an Intermediate Ampliﬁer #1, and
a Driver Ampliﬁer #2, No user tuning adjustments are needed or provided.
Mixer: This section consists of a balanced mixer being driven from the LO injection
input via the 180° balun and an IF signal input via a low pass ﬁlter. A microwave short
is formed by a capacitor. The heterodyned product is coupled out of the diodes by a
printed Wilkinson hybrid. This hybrid will substantially reduce the LO injection signal at
the output due to its out of phase cancellation, The microwave signal is ampliﬁed by a
low noise, 50~0hm hybrid ampliﬁer that is biased by a resistort Decoupling of the supply
is by a printed decoupling line, two capacitors, and a resistor.
Intermediate Amelitrer #1: This ampliﬁer consists of two identical bi-polar transistor
ampliﬁers in cascade. A transistor base bias via two resistors is derived from a common
collector resistor. As current attempts to rise above the nominal 14 mA, voltage to the
base circuit is reduced, thus causing a stabilizing feedbackt A printed decoupling line,
two capacitors and a resistor provides base and collector decoupling.
Drive Amglitrer # : This ampliﬁer consists of two similar FET transistor ampliﬁer stages
in cascade. From a common module feedthrough ﬁlter, +10 VDC is supplied to each
transistor’s drain circuit via a printed decoupling 1ine and two capacitors. From a
common -12 volt feedthrough, negative gate voltage is divided down and calibrated by
two resistor networks. The potentiometers set the drain current of each device.

MICROWAVE SYNTHESIZER
The microwave synthesizer module determines the microwave upconverter mixer input and
transmitter output operating frequency. The operating frequency is determined by programing
of the phase locked loop ﬁ'equency synthesizer. Miniature DIP switches SW] and SW2 set N
counter and A counter PLL programming inputs. A 10 MHz input reference signal applied to J 1
determines the frequency stability of the PLL.
The synthesizer module uses a microwave prescaler, dual modulus prescaler, and internal
dividers to reduce the 10 MHz reference and microwave voltage controlled oscillator (VCO)
frequencies to 25 kHz for the 09—049 series or 125 KHZ for the 09—073 series. These signals are
applied to separate inputs of a phase detector. Input signals of equal phase generate no change
in output. Should the VCO deviate in frequency, a phase shiﬁ is detected causing an
integrator/low pass ﬁlter to generate a DC control voltage proportional to the offset frequency.
This control voltage is applied to the microwave VCO to return it to the selected frequency
The microwave local oscillator frequency is derived by adding (or subtracting in certain cases)
the desired transmitter channel frequency to the incoming IF frequency:
EXAMPLE:
Visual Output Frequency + Visual IF = Microwave LO Frequency
2501.25 MHZ + 45.75 MHZ = 2547 MHZ
Aural Output Frequency + Aural IF : Microwave LO Frequency
2505.75 MHz + 41.25 MHz = 2547 MHz

FINAL AMPLIFIER
The Final Ampliﬁer module receives an input signal at J1 and provides an ampliﬁed output at
B. The ampliﬁer module consists of seven FET ampliﬁer transistors operating in a two driving
ﬁve parallel conﬁguration. Printed input hybrids (H2, H3, and H4) split the input signal to drive
the ﬁve transistors equally. Output hybrids (H5, H6, H7, and H8) recombine the ampliﬁed
signals to a common output.
Biasing of each FET is identical, therefore, only Q1 is discussed. +10 VDC is supplied to the
drain through an EMI feed through filter, A printed decoupling line, C63, C64, C5, and R6
decouple the drain circuit. Negative 12 volts DC gate bias enters the module through a common
EMI feed through ﬁlter. This voltage is divided and calibrated by resistors R2, 16, and VRl.
VRl sets the operating drain current. A printed decoupling line, C62, C3, and R4 decouple the
gate Circuit No tuning adjustments are needed or provided,

The notch ﬁlter is the last module the signal passes through before exiting the transmittert
The purpose of the notch ﬁlter is to correct for intermodulation distortions There are
four notches in the ﬁlter which are divided into two sections. The sections are composed
of two non-adjacent notches as shown in the diagram below.

Notch #1 Notch #3 Notch #2 Notch #4
Section A Section B
FIGURE [3-0032-1
For digital use:
Section A consists of Notches One and Two which are tuned to minus 1.5 times and
minus 1 times the channel bandwidth with respect to the center frequency of the channel
(Fc - BW and Fc - 1,5 BW). Notches Three and Four, Section B, are tuned as section A,
FC+BWand Fc+ 1.5 BW.
For analog use:
Section A consists of Notch One and Notch Two which are tuned to the frequency of the
video carrier (fv) minus the separation of the frequency between the Visual and aural
carriers (fv — Q) and 2(fv » fA). Therefore, Notch One and Notch Two are tuned to fv - (fv
- £4) and fv - 2(fv - fA). Notch Three and Notch Four, Section B, are tuned for fv + (fv -
ﬁt) and fv + 2 (fv - Q).
(The notch ﬁlter is factory tuned for a precise frequency response before the transmitter is
shipped.)
Note: Each section may be tuned either above or below the channel center frequency,
but no two adjacent notches are to be tuned in the same direction.

Q QWAVE Motherboard , 35-066
MOTHERBOARD
The Motherboard performs a variety of functions allowing operation for both analog and
digital applications, Located on the underside of the transmitter, it provides the majority
of the interconnections among other circuit boards and modules. The board contains
linear power supplies, current sampling resistors, metering adjustments, one +12 volt
power supply fuse, and three +11 volt power supply fuses.
Interconnectinns: Power and logic signals are routed to/from various module or circuit
card assemblies Via the motherboard and main harness. Consult the interconnection
diagram, to be provided at a later date, for guidance. The Synthesizer, IF Processor, and
ampliﬁer modules plug directly into this board for DC supply and monitoring
Linear Power Supplies: -12, + 12, and +5 volt linear power supplies are located on this
printed circuit board. These DC power supplies provide power to operational ampliﬁers,
comparators, gating circuits, and other modules.
0 The negative lZ-volt circuit consists of a center tapped full wave rectiﬁer, ﬁltering
capacitors, and an adjustable regulator. The voltage can be calibrated adjusting VRS
on the board, while monitoring TP], Short circuit protection is provided internal to
the regulator.
Note: This adjustment should only be done in operation mode, due to FE T gate pinch

LOGIC CONTROL P.C. ASSEMBLY
This plug-in circuit board serves to control the operation of the upconverter/ampliﬁer by
providing eight basic functions:
A. Auto ON/OFF Transmitter Conuol E. Thermal Interlock
B. Video Presence Control Bypass F. External Ampliﬁer Interlock
C. Power Supply Comparator Interlock G, Local Standby Control
D. FET Bias Interlock H. Remote Standby Control
Tum ON of the transmitter/power supply occurs upon logic satisfaction of AND gates U3A and
U3B. With all AND gate inputs satisﬁed with TTL highs, the output of USB is high tuming on
Q3. Q3 sinks current from Q4, keeping it in cutoff allowing +5 VDC to the power supply
enable and turn on the switching power supply. Failures or missing input signals disable the
switching power supply.
The Logic Control Board contains three status LED’s. Under normal operating conditions all
LED’s illuminate verifying successful tum ON and satisfaction of conditional logic: Red LED
Dl verifies that each ampliﬁer module has proper -12 VDC gate bias. Green LED D2 indicates
the presence of an applied video input signal. Yellow LED D3 veriﬁes the switching power
supply enable.
A. Auto ON/OFF Transmitter Control: Transmit ON/OFF operation is initiated by a TTL
high (>3.l volts) from a modulator video sense circuit, receiver auto-on circuit, or any
other external control voltage applied to board inputs at connector E] (V) originating
from rear panel connector J—l, pin 1, When a video presence voltage is available,
Darlington transistor Q2 is biased ON illuminating D2, the Video Presence Green LED.
The turn ON signal is delayed to U3B pin 4 by the time constant of R22 and C]. This
prevents an instantaneous turn ON of the transmitter due to nansients.
B. Video Presence Control Bypass: A video presence control bypass switch SW-l is
located on the side of the PC board assembly. The normal position for this switch is
DOWN. DOWN is the equivalent of OFF. When the switch is down, an external input
video presence signal must be supplied to turn the transmitter ON. This signal typically
originates from a video presence board contained inside the modulator. When this
switch is positioned UP, this places the transmitter into BYPASS mode or in a constant
ON condition by providing +5 VDC to the input of AND gate U3B pin 4. This enables
the transmitter to continue transmitting even though there is no video signal present.
C. Power Supply Comparator Interlock: +ll VDC switching power supply voltage is
sampled and monitored by comparator U2B. A series resistive summing circuit
consisting of mother PC board fuses F1fF2/F3, resistors R34, R35, R36, and R14 form a
voltage divider at a nominal 3.0 VDC input to pin 3 of the comparator.

Q COMWAVE Logic Control 7 33-124
A nut-mm Company
A ﬁxed threshold voltage of 35 VDC is applied to the inverting input of U2B pin 2 and
creates a “window” for monitoring the power supply. The operating window is 8.95 to
12.4 VDC. A switching supply voltage sample within the window causes the
comparator to output a logic low and sink the +5 VDC pull up voltage from the gate of
SCR D4. With D4 disabled, a logic high is present on U3A pin 9. Satisfaction of AND
gates U3A and B pass a tum ON signal through Q3. With Q3 biased on, Q4 remains in
cutoff, The +5 VDC source powers yellow Power Supply enable LED D3 and supplies
a turn On signal to the switching power supply.
A switching power supply deviation above +124 VDC causes the comparator to output
a logic high and enable the SCR gate. The SCR ﬁres and pulls U3A pin 9 low removing
the power supply enable signal.
Comparator UlOB on the Diagnostic Interface Board determines the low limit
parameter. Any open mother board fuse(s) reduces the comparator input voltage and
toggles UlOB low resulting in illLunination of the RED front panel PWR SUPPLY
diagnostic LED.
D. FET Bias Interlock: Negative 12 VDC gate bias from driver and ﬁnal amp are fed back
to edge card connector E-1 pins M. N, P, R, and S. These inputs provide protection in
the event of a low or missing ampliﬁer gate voltage. For each circuit, a comparator with
ﬁxed voltage reference of +1 .15 VDC on the non—inverting input and gate bias sample
on the non-inverting input is used. The -12 VDC gate bias is reduced by an input
resistors and is combined with +5 VDC providing +75 VDC to the inverting inputs.
Absence of -12 VDC allows the inverting input to be higher than the non-inverting input
causing the comparator to toggle low. A low output from any of the ﬁve comparators
sinks the pull up voltage, This action extinguishes the red gate bias LED DI and applies
a logic low to AND gate U3A pin 10, shutting down the transmitter.
Illumination of the on board red status LED (D1) indicates that all module gate bias
inputs are present.
E. Thermal Interlock: A thermal interlock is provided to shut down the transmitter in the
event the internal temperature exceeds +160 degrees Fahrenheit (+71 degrees Celsius).
Actuation of the thermostat closes internal contacts and supplies a ground to monitoring
circuitry. The ground removes the TTL high from U3A pin 12 thereby disabling the
+11 VDC switching power supply, The thermostat automatically resets after a cooling
period.
F. Extemal Ampliﬁer Interlock (Remote B t: A remote/agile standby control is available for
extemal ON/OFF control of the transmitter without any delays. This interlock return is
available at E1 pin T or rear mounted connector I 1 pin(2). Voltage is held at +5 VDC
by R26/D6. A ground placed on this line pulls AND gate U3A (l 1) low and disables
both the interlock and +1 1 VDC switching power supply.

G, Local Standby Control: Local standby control of the transmitter is achieved by rotating
the front panel function switch to standby. The function switch places a low resistance
on R29, which lowers the voltage to approximately 0 volts at U3B—5 for a TTL low.
The output of AND gate U3B toggles low to disable the +1] VDC switching power
supply.
H. Standby Control (Remote A : A remote standby interlock tum OFF return is available at
E1 pin 4 or rear mounted connector J2 (19). Voltage is held at +5 VDC by R28/D7. A

Q COMWAVE Diagnoslic Interface Board — 33-131~AA
DIAGNOSTIC INTERFACE BOARD
The Diagnostic Interface Board, located on the chassis underside, receives various signals,
performs comparisons to set reference levels, forwards compared outputs to the front panel LED
Display board, and provides remote fault status monitoring. The interface board determines
amplifier module status by monitoring +11 VDC switching power supply drain currents dram
through motherboard series sampling resistors.
Each module has associated diagnostic circuitry which monitor the operating currents.
Excessive or lack of proper current draw causes the respective comparator output to go low and
illuminate the applicable front panel diagnostic LED.
