Keysight
The Keysight M9421A is a PXIe vector transceiver module. The Keysight M9421A has a 60 MHz to 6 GHz frequency range. The Keysight M9421A has 160 MHz maximum RF bandwidth.[1]
The M9421A uses FPGA-accelerated measurements and deep software to support rapid solution creation and faster throughput.[2]
The M9421A supports modulation and analysis bandwidth up to 160 MHz.[2]
The M9421A fits in manufacturing test for wireless components, power amplifiers, and RF front-end modules.[2]
The M9421A also fits radio transceiver design validation, production test, and development and manufacturing test for connected devices.[2]
The M9421A can be used in an eighteen-slot PXI chassis with up to four VXT modules in one chassis and a single M9300A frequency reference.[2]
The M9421A is used for power amplifier and front-end-module design validation and manufacturing.[2]
The M9421A is used for radio transceiver design validation and production test.[2]
The M9421A is used for radios and other connected devices that rely on wireless communications.[2]
