A1: - A2 RF Converter: Mixes 70 MHz IF with the L.O. frequency (Synth.)

A2:

- AR1: Linear Amplifier, electrically controlled by the

Amplifies RF to 1 watt (LOS) or .25 watt (TROPO)

VVA Control input. Provides 30 dB of gain

HY1: Impedance matching. Prevents power from being reflected back into the IPA, instead routing it to ground

CR1 RF Detectors: - A1CR1: Monitors the input to the A2 IPA ASSY- A2CR1: Monitors the output of the A2 IPA ASSY- A3CR1: Monitors the final RF output level

4.4 - 5.0 GHz

Electrically controlled by the VVA control input

Factory set, limits the maxoutput of the upconverter

Generated if A2 input poweris below normal

30 dB down sample

Produced if output of A2 is below normal

Factory Set DC reference voltages

Compares the detected RF Output Level from Buffer U1 with the Fault Reference Voltage from A3A1.

- With the RF Output Level within the threshold limit of the detector, U12 output is at a Low TTL level, which keeps the Fault Reporting Relay K2 energized and DS1 extinguished.

- If the output exceeds the fault threshold, U12 output is a high TTL level which deenergizes K2 and illuminates DS1 via LED Driver U9.

-- With the relay deenergized, the UP CONV -1 FAULT RET from the Alarm Monitor is routedback to the Alarm Monitor as the UP CONV -1 FAULT signal, causing the Upconverter Alarmto illuminate on the Alarm Monitor Panel.

FIXED VOLTAGES

Energized in LOS, Deenergizedin TROPO

A4: Monitors the input/output of the power amplifier. Compares the input/ouptut to selected reference to produce the AGC (VVA Control) in order to maintain a constant output power level.

- RF Inhibit (+14.8 VDC): Shuts down the Upconverter by causing the AGC Circuit to use the Limit/Fault Ref Control to induce 40 dB of attenuation, effectively shutting the Upconverter down.

If input to the Downconverter exceeds 50 mVthe Downconverter will send out an Inhibitto the associated Upconverter, shutting it down.

- The Logic: If your receivers are beingoverdriven, it is more thanlikely caused by your own transmitter.

(Inhibit Command)

Sent From the HPA under the following conditions:

2) Antenna has high reflected power

1) Klystron has high VSWR

3) Momentarily when S1 Waveguide switch changes position (DL/ANT)

A1A3: Level Conversion- Storage and distribution to the A1A7 Trigger control

A1A7: Trigger Control- Generates Timing/Triggers

-- 3 Triggers to FAINT & 2 Triggers to each Inverter

- Processes Standby & OFF Faults from Logic CCA- Automatically resets 2 successive Faults occurring

within 9 seconds.

-- Third Fault within 9 seconds will cause the HPAto go into Fault condition

A1A6: Trigger Amplifier- Shapes and Amplifies- Used by five SCRs in the Inverters & FAINT

A1A8: - Monitors run-up of FAINT- Monitors Beam Voltage in HVPS

-- Sends pulses which vary the B & C Inverterwhen switching between High & Low Power Modes

A1A5: Generates Filament Voltage for the klystron & monitorsFilament Current to insure proper level and operation

Ref: T.O. Chapter 5, Pg. 5-6/5-46

A9: Converts the 208 VAC input to a rectified 280VDC to providea controlled method for HPA turn on

A6, A7, A8: Converts 280 VDC to 220 VAC @10kHz

- A & B are used in Low Power mode- A, B, C are used in High Power mode-- Produce 10 KHz sinewave used to create Beam Voltage

- Controlled by the Range Switch in the BITE compartment

A3: Uses 10 KHz sinewave from Inverters to produce either 7.8 kV (High Power) or 6 kv (Low Power)

RF MONITOR: Measures input & output power levels of the HPA.

- Takes RF samples at various test points

HPA FAULT MONITORING: Monitors all HPA critical functions.

- Faults are categorized as OFF and STANDBY

(Determines LOS/TROPO Mode)

(Prevents Alarms during warmup)

3A1: Mixes the L.O. frequency from the TX Synthesizer with the 70 MHz IF to produce a difference (Lower Sideband)frequency (4.4 - 5.0 GHz)

- Amplifies signal in the IPA to +29 dBm (LOS) or +24 dBm (TROPO)

2A2: Applies 42 dB of gain

- Compression adjust will allow the klystron to operateat optimum levels throughout the frequency spectrum

- All frequencies within the bandpass are amplified to within +/- 1dB of each other

- Drive Level (Power level to be used for Compression Calibration)is adjusted by AT3

-- 400 watts/High Power-- 200 watts/Low Power

W6: Simulates the Non-linear portion of the Klystron

- Used only during Calibration-- Signal goes from S2J3 to S2J4, through W6,

and then from S2J2 to S2J1 ( See T.O. Pg. 5-47,Para. 5-6.3.3.2.a)

Momentary Toggle Switch

When in the "CAL" Position, will causethe relay in S2 to energize, insertingW6 into the signal path

Compression Adjust Attenuator

- Set to: 200 watts (Low Power), 400 watts (High Power)

Gain Compression Circuit, C&D Pg. 62 (2A2A2, 2A2A4, 2A2AT3, 2A2S2): - Ensures that the Klystron is operating at its'maximum efficiency throughout the frequency spectrum

- All frequencies within the Klystrons' passbandare equally amplified to within +/- 1dB

- Loopback circuit: Provides a calibrated means of applying the TM Modulator IF output to any individual ora combination of several TM Demodulatorinputs.

- Antenna Alignment circuit: Converts the IF signal into a DC voltage,proportional to the RSL of any one of foursignal levels.

ALARMS

HIGHEST PRIORITY ALARMS

CONFIG BER

A1: Interface between the Alarm Monitor and equipment subsystems. Prioritizes using Programmable Logic Array (PLA) to eliminate the "Christmas Tree" effect.

A2: Five basic functions: - Generates 2KHz timing Reference - Accepts, processes, and routes BER information - Performs additional processing on A9 Fault Display and routes signal to the A3 Message Generator - Provides alarm and interface operations - Processes Configuration Alarm inputs

S 1 (TX RADIO)

S1 (TX CABLE)

(RX CABLE)

A4: Provides DCV & Switches for inserting the Station ID & Subchannel.

A3: Generates One (1) sequence, consisting of four (4) blocks, with 20 characters per block ( Station ID, Van Status, current BER)to be sent to CNCE. Each block will ID two internal Equipment Faults, for a total of up to 8 unique faults.Upon the 9th fault (unique) being ID'd, CNCE will receive what is known as a MAJOR MAJOR Alarm.

VOCU: DVOW provides secure, half-duplex System orderwire that operates at a 16 Kb/s data rate. The VOCU has 5 channel inputs (4 cable, 1 radio). Interfaces with the ROCU. Converts Analog (From the ROCU) to Digital prior to encryption by the KY-58.

Controls access to, and configuration of, the A2 Electronic Bridge CCA

Also sent to the ROCU A1 VINSON: - A/D & D/A conversion

- Encrypts/Decrypts orderwire- Configured to work only

in cypher mode

Can only perform these functions one directionat a time. This is what limits it to half-duplex.

Steady tone: Alarm @ CESE PanelBeeping tone: Incoming call

A2 Electronic Bridge: Controls access to the DVOW via the Modem Select switch.

- Monitors DVOW activity- Connects GM 1-4, LSCDM & TM- Runs on a 1st come, 1st served basis- If inactive, on the entire link ( 80seconds) it will initiate a self-test- Sends VOCU faults to the CESE (Alarm Panel)

VINSON TM RING CODEENCODE/DECODE

TO/FROM A3 CCA

DECODER

ENCODER/DECODER

A3 Encoder/Decoder: Interfaces the A4 & A2 CCAs - Decoder decodes & compares RX Ring Codes to the S3 settings. There must be 16 consecutive signal code matches before a RX CALL RING will be initiated ( to prevent false rings). - Encoder encodes ring signal codes for TX ring generation (16 bit code) A4 Vinson Buffer: Acts as a buffer between the A2 CCA and the KY-58. Allows asynchronous operation

of the KY-58 with respect to system timing. Limits the DVOW to 2.2 minutes of continuous operation.

- The VINSON does not provide a clock. The A4 CCA must recover a clock from transitions contained within a 16KHz externally provided clock ( from TM ). The data is then shifted out of the buffer circuits and in to the Vinson at that 16 KHz rate. - Also interfaces the Analog side of the Vinson with the ROCU via the Remote Mode Switch

A5 Call & Fault Indicator:

- Controls busy line, sends alarm staus and mutes the buzzer- Interfaces between the VOCU & ROCU via the A6 front panel switch- Provides audio/visual indications for a RX Ring

See KCS 6407B, Pg. 1-2

- In Secure Mode, no audio is processed to/from the ROCU
