PCM Recording System
PCM Recording System
The PCM Recorder is made up of two separate and independent channels. Each channel receives a PCM-106 input (NRZ-L, B.R), decodes the received data stream and records it on CF flash memory.
The PCM Recorder synchronizes the recorded data to the internal system time. The recorded Flash card provide recorded flight parameters as a function of time.
The Flash card contains a special setup file providing the PCM Recorder with predetermined user setup information.
For applications that require recording PCM together with data from other varied sources, use the Telemetry Data Recorder.
