Telemetry recording and reduction equipment for shipboard support of missile exercises

The Telemetry Recording and Reduction Equipment (TRRE) is designed to process both the pulse amplitude modulation (PAM) telemetry data formats of existing missile designs and the pulse code modulation (PCM) data formats of evolving missile designs. Through preprogrammed telemeter formats and programmable decommutation tables, the TRRE design minimizes the required operator interface. The decommutation hardware configuration is programmed by a microprocessor. The TRRE system comprises two signal-processing chassis, a magnetic tape recorder, and an oscillograph; interfaces are provided for an external printer and spectrum analyzer. The primary purpose of the TRRE on board a ship is to document the missile firing by making a telemetry recording and providing a 'quick-look' and analysis capability at the completion of the flight.
