DESCRIPTION AND DATA

1-8. DESCRIPTION. A single RSPU is used in each AN/ML()-34 system. The RSPU

interfaces the four system receivers to other units in the system. It also

provides received signal processing functions. Received signals are processed as

follows:

a. Carrier presence detectors monitor the narrowband IF output of the receiv-

ers to provide activity indicators.

b. NATO tone detectors monitor the audio output of the receivers providing an

indication when the tone is detected.

c. A signal data processor provides data for a panoramic (PAN) display of the

received signal.

For a further description of the RSPU, refer to TM 32-5865-060-10, System

Operator's Manual.
