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 R&S SMBV-P101 speed-optimized GNSS production tester simulates separate satellites for the four GNSS navigation standards in the L1/E1 band specifically for these production tests.
According to Rohde & Schwarz, the four GNSS satellite signals can be activated individually, each with a high dynamic range of 34 decibels, with power level changes made on the fly without interrupting the signals, thus enabling users to simultaneously perform independent sensitivity tests for each navigation system. The 1 pps or 10 pps GNSS marker allows precise time synchronization between the tester and the device under test. Pure, level-stable continuous wave signals can also be generated to calibrate the test setup or to simulate interferers, the company says.
The R&S SMBV-P101 option additionally offers test functions for characterization of GNSS chipsets. As a result, a receiver’s ability to handle high movement dynamics can be verified quickly and effectively, according to Rohde & Schwarz. To do this, users may access both predefined and user-defined Doppler profiles, from which the R&S SMBV100A automatically generates the appropriate satellite signal.
The R&S SMBV-P101 GNSS production tester package for the R&S SMBV100A is now available from Rohde & Schwarz.
