DS-HES-C Radio Altimeter Simulator (Core module)

  • The core module of the DS-HES altimeter tester can be sold separately or integrated into higher-order assemblies. These assemblies can be configured to meet various performance specifications in order to be compatible with the customer’s form, fit, and function requirements.
  • Compare with traditional SAM(surface acoustic wave) delay line systems, DS-HES series products have more advantages such as a wide working frequency band,  high straight suppression ratio, triple transit signals that are immeasurable, long-life operation without calibration, and high work reliability.


Features of the Core module of the Altimeter Tester Simulator

※ Wide simulated height range(0 to 22000 above );
※ High simulate altimeter accuracy(≥1‰);
※ Optional simulate configuration(support more than 210 configurations);
※ Manual switch and automatic switch;
※ Volume miniaturization, strong electromagnetic compatibility, high work reliability;
※ Multiple control modes: UART, LAN, etc.
※ Various standard test platforms interfaces such as PXI, VXI, and LXI.

Application of the Altimeter Tester Simulator

Place: Radio altimeter for radar, AEW, satellite, helicopter, etc.

※ Measure the accuracy of the altimeter
※ Measure the sensitivity of research and tracking
※ Measurement of another parameter
