Microdyne 1100-AR Telemetry Receiver 1111-VT RF Tuner 52-88 MHz 3 Modules

Microdyne 1100-AR Telemetry Receiver 1111-VT RF Tuner 52-88 MHz 3 Modules

The Microdyne Corporation 1100-AR(01) is a modular rackmount telemetry receiver built for ground-station reception and demodulation of RF telemetry signals. The 1100-AR mainframe accepts plug-in modules that handle RF tuning, signal demodulation, and intermediate frequency filtering, making it a flexible platform for a variety of telemetry reception tasks. This unit includes three installed modules covering the full receive chain from RF input through PM demodulation and IF filtering.

Applications

Microdyne Corporation was a leading U.S. manufacturer of telemetry ground station equipment from the 1960s through the 1990s, supplying systems to NASA, the U.S. military, aerospace test ranges, and defense contractors. The 1100-AR series telemetry receiver was designed for PCM, FM, and PM telemetry reception — receiving RF signals broadcast from aircraft, missiles, rockets, drones, and spacecraft during flight test and range operations. The modular plug-in architecture allowed ground station operators to configure a single chassis for different frequency bands and demodulation schemes by swapping modules, which was a significant advantage at busy test ranges handling multiple programs. The 52-88 MHz RF tuner module covers the lower portion of the IRIG standard telemetry frequency bands used historically by U.S. government and military range operations. Equipment of this type was used at major test facilities including Edwards Air Force Base, White Sands Missile Range, and NASA's tracking stations. The 1100-AR is also found in use by universities and research organizations for legacy telemetry data recovery projects. Collectors and aerospace surplus buyers also seek these receivers for their historical significance in Cold War-era flight test programs.
