The Keysight M9361A is a 1-slot 3U PXI downcoverter that converts microwave signals from 2.75 GHz to 26.5 GHz into baseband frequency signals centered at an IF frequency of 500 MHz
The built-in pre-amp enables very low level signal measurements, down to -160 dBm, and the built-in calibration simplifies system power budget calculations.
