Applications
FM data detectors were integral components in satellite ground station receiver chains, particularly for Australian AUSSAT systems. This unit handled demodulation and detection of frequency-modulated telemetry signals from space-based platforms. Typical deployment involved integration into larger telemetry processing racks alongside multiplexers, decommutators, and recording equipment.
This Hughes Aircraft 3878521-100 FM Data Detector was pulled from a working environment where it was in active use. It has been inspected and is in good used condition overall. The chassis, front panel controls, and rear connectors all appear intact and undamaged. The bottom plate is missing, as noted in the listing title and reflected in the price. Interior photos show the PCBs, wiring, Acopian AC-to-DC power module, and Vectron crystal oscillator are all present and visually intact. Some light surface wear and aging are consistent with prior operational service. Please view our photo set and contact us if you have any questions.
