Dynamic Sciences R-1250 Receiver
The model R-1250 [...] is a solid-state radio frequency receiver that provides means of detecting and measuring signals associated with the requirements specified for electromagnetic analysis, TEMPEST, spectrum analysis, and frequency surveillance. The receiver circuits are enclosed in a rugged compact chassis, and process RF signals in the form of a continuous wave (cw) or modulated carriers, both amplitude modulated (AM), and frequency modulated (FM), within the frequency range of 100 Hertz to 1.0 Gigahertz. Two modes of the receiver operation are incorporated into the instrument, a manual mode and a remote mode that uses computer control for tuning and function selection. The design of the model R-1250 receiver meets or exceeds the requirements as outlined in NACSIM specification 5100A
