Apollo Command Module (Block II) Pulse Code Modulation (PCM) Telemetry Assembly, measuring approximately 13 x 7 x 14 and weighing 42.1 pounds, manufactured by Radiation, Inc., Melbourne, Florida. In fine condition. The unit received and sampled analog, parallel digital, and serial digital information, which consists of astronaut biomedical, spacecraft operation, and scientific data. It then converted the data to a single serial output for transmission to Earth. This single-output signal was routed to the Premodulation Processor for transmission to the ground or to Data Storage Equipment. Oversized.
