Rohde & Schwarz Offers Fast Production Testing for Receivers

摘要

Rohde & Schwarz now offers a new, speed-optimized production tester - the R&S SMBV100A vector signal generator equipped with the R&S SMBV-P101 package. During production testing of modules and receivers for satellite-based communications, the basic GNSS signal reception and the connection between the antenna and GNSS chipset need to be checked.The GNSS production tester simulates separate satellites for the GPS, GLONASS, BeiDou and Galileo navigation standards in the L1/E1 band specifically for these production tests.The satellites can be activated individually, each with a high dynamic range of 34 dB. Level changes can be made on the fly without interrupting the signal, enabling users to simultaneously perform independent sensitivity tests for each navigation system.The 1 pps or 10 pps GNSS marker allows exact time synchronization between the tester and the device under test (DUT). Pure, level-stable continuous wave signals can be generated to calibrate the test setup or simulate interferers.
