TM 11-7440-232-12/NAVELEX 0967-LP-275-5010

Digital Receiver

·Receives a stable 4.8 MHz timing frequency from the RF oscillator.

·Provides two outputs: one for data retiming within the internal system, and the other

for retiming external sources.

·May be operated at 600, 1200, or 2400 bps.

·Controls transmitter clock.

Data Carrier Alarm

·Provides four alarm circuits which monitor the transmitter and receiver data

and carrier signals.

·Provides fail-safe alarm output to peripheral audible/visual alarm if trouble occurs in

any monitored signal path, or in the power supply.

RF Oscillator
