The Keysight M8920A is a PXIe radio test set engineered for high-throughput manufacturing and functional testing of radio devices across tactical, public safety, and commercial applications. It combines PXI modular hardware, specialized software, and integrated measurement capability into a single scalable chassis platform.
The M8920A delivers broad multi-format signal support with configurable frequency coverage to 3.8 GHz or 6 GHz. Generator and analyzer bandwidth scales to 160 MHz, with modulation and analysis bandwidth available at 40 MHz, 80 MHz, or 160 MHz depending on configuration. Memory options range from 256 MSa to 512 MSa.
