® ® ® Key features R&S SMBV-K360, R&S SMBVB-K360, R&S SMW-K360 1 Key features The test suites R&S SMx-K360 provide ERA-GLONASS tests with the sequencer tool R&S CMWrun. The tests are performed on a connected in-vehicle system (IVS) for ERA-GLONASS. The tests are as closely aligned with the selectable test specifications as possible. - Page 6 ® ® ® Key features R&S SMBV-K360, R&S SMBVB-K360, R&S SMW-K360 Test case Test purpose 5.12 - Tracking and acqui- Verifies the sensitivity of the GNSS navigation module in signal acquisition sition sensitivity mode and in tracking mode. The minimum navigation acquisition power is determined by decreasing the signal power stepwise.
