The M9421A from Keysight Technologies is a VST PXIe Vector Transceiver that consists of a vector signal generation and analysis in four slots of a PXI Chasis. The VST is purpose-built for rapid solution creation and faster throughput in manufacturing test of wireless components , power amplifiers, and RF front-end modules. It operates from 60 MHz to 3.8/6 GHz and provides a 160 MHz I/Q bandwidth in both vector signal generation and analysis. This transceiver is ideal for power amplifier, front-end module validation and radio transceiver validation and production test.
