  • Bandwidth Settings: 750 Hz, 1.5 kHz, 3 kHz, 6 kHz
  • Loop Settings: 1% / 0.1% selectable
  • Power: 115V / 230V switchable, 0.5A
  • Unit only; no manual or accessories included

Applications

This equipment was used in telemetry reception systems for tracking and data acquisition in space programs and aerospace communications. Decom Systems units of this type were standard in ground stations and mobile platforms for demodulating and synchronizing satellite telemetry streams. Compatible with systems requiring real-time PSK/PCM signal processing across multiple bandwidth and bit rate configurations.

Condition: Used
This Decom Systems DSI 7376 PSK/PCM Bit Synchronizer and PSK Demodulator has been inspected and appears to be in good used condition. The front panel controls, knobs, switches, and meter are intact and show normal wear consistent with lab or ground station use. The BNC connectors on both the front test outputs and the rear panel I/O array appear undamaged. The chassis and honeycomb top panel show light surface scuffing typical of rackmount equipment. A PanamSat asset tag is present on the front panel and a PAS Capital barcode label is affixed to the rear panel. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
