The R-1550 TEMPEST Receiver complies with the NSA TEMPEST Test standards. As well as all test parameters  required for TEMPEST testing, frequency range, accuracy, stability, tape size, attenuation, gain, etc. 


The EMI Test series of receivers is know as the DSI-600. A fully compliant test system for all your EMI Testing needs. (Compliant to CISPR 16-1, FCC, ANSI, DO-160, EN, MIL-STD-461). The receiver is complete with an embedded high speed PC & powerful software operating in a Windows environment. The DSI-600 receiver may operate in three modes.:1) Spectrum Analyzer, 2) Receiver System Mode, and 3) Remote Mode (Driven by external controls.) 



The Surveillance system family of receivers and RF ancillary equipment Features exceptional RF measurement sensitivity accuracy, flexible signal collection, storage, retrieval and report preparation capabilities. Many signals that defy analysis by other means can be understood by an operator when presented in a visual format. The RG-1000A Raster Generator makes this possible. This instrument contains a unique combination of digital and analog circuitry that allows conversion of almost any repetitive electronic signal into a pictorial display. 



Our Antenna’s and Accessories support electronic field strength measurements ranging from 20 Hz to 40 GHz. We also support magnetic field strength measurements from 100 Hz to 20 MHz These devices are suitable for shielded enclosure or general field use. Our product line consist of Broadband Antennas, PreAmplifiers, LISN’s, Comb Generator, Near Field Probes, Clamps and more.
