Some models also feature built-in EMI/EMC filtering for MIL-STD-461F that typically eliminates the need for additional in-line power conditioning/EMI filtering devices in military embedded systems.

  • MMW Field Sensors

    ITS-9050 - Innovative Technical Systems

    The Innovative Technical Systems ITS-9050 Detector is a sensitive, harmonic mixing detector designed to measure millimeter-wave free-space radiation. It is ideal for measuring radiation patterns of antennas inboth the near and far-field. The ITS-9050 employs a free-running dielectric resonator oscillator (DRO) and an integrated harmonic mixer with a waveguide RF input that either connects directly to a circuit under test or to an antenna for radiation detection. The resulting IF is amplified and detected by an IF log-detector that drives a front panel LCD voltmeter to provide an indication of signal strength. A DC output voltage from the log detector is available on a BNC connector to drive external data acquisition instrumentation. Also, a sample of the IF output is provided for measurement on a spectrum analyzer.
