  • Full Band Phase Shifters

    STP-18-10-M2 - ERAVANT

    Full band phase shifters are micrometer-driven, waveguide-based phase shifters. The configuration of the micrometer-driven phase shifters is similar to that of level setting attenuators, where the phase shifting is caused by an E-plane dielectric insert in the rectangular waveguide. The amount of phase shifting is directly dependent on the volume of the insert. The VSWR and the insertion loss of these phase shifters are dependent on the frequency. The below standard offering covers the frequency range of 18 to 110 GHz and a phase shifting range of 180 degrees. These micrometer-driven phase shifters are typically used to introduce a certain amount of phase shifting when the absolute number is not a focus.

  • Range-Doppler Target Generators

    ATG9100 - Innovative Technical Systems

    The ATG-9100 is an example of a laboratory-quality instrument that will simulate complex target motion. Microwave signals from the speed camera enter the instrument through an integrated antenna which is then downconverted and digitized. Target simulation data is added to the digitized signal to provide range and Doppler information. The modified digital data is then converted back to an IF and upconverted to the original microwave frequency of the speed camera and radiated back through the antenna. Since the ATG-9100 can be phase-locked to an external 10 MHz reference standard, this instrument is suitable for use as a calibration standard for speed cameras.

  • Computer-Based Instruments

    GT210PXI - Guide Technology, Inc.

    GuideTech’s GT210PXI 3U form factor, meets industrial standard chassis with an expandable platform, achieving optimal test system with optimal cost. The ability to precisely resolve frequency and time yields both increased accuracy as well as reduced measurement time. For example, with the GT210PXI-1 you can determine any frequency to 0.01 part per million (eight digits) in just 1 mS, and resolve each time measurement to 8pS. Couple that with 2300 measurements per second, one of the fastest rates available and you can acquire more data in a single second than a typical GPIB counter can in one minute! Faster measurements and higher resolution, along with built-in statistics functions give you a more thorough analysis of your signal. Standard deviation, peak to peak jitter, or a graph of the measurements are available at the push of a button.​
