RF signal source for infotainment, navigation

’s software-defined AST-1000 Signal Tester is aimed at validating all common infotainment protocols and can evolve as users’ test needs change, including handling navigation, video, and connectivity testing. The AST-1000 can generate all common radio signals (AM/FM, DAB, DRM, HD Radio, and Sirius/XM), handles digital video signals (ATSC, CMMB, DVB-T2, and ISDB), and can simulate all common GNSS signals (BeiDou, Galileo, GLONASS, GPS, and QZSS). The AST-1000 uses a framework from National Instruments, which enables users to add a PXI-based waveform generator to generate any number of waveforms using NI LabVIEW toolkits such as WiFi, Bluetooth, , and WCDMA for module-level validation.

The AST-1000 is an extensible platform that can accommodate changing standards, new protocols, non-RF (for example, CAN), and additional applications for wide-ranging product test and validation needs. The signal tester uses a multiconstellation and multifrequency GNSS simulator powered by M3 Systems and features an interface for quick signal generation and easy test setup. It is rackmountable and can handle lab validation along with functional and end-of-life testing. Its standardized APIs enable the user to upgrade from older Averna RF signal-source products.
