Key Features & Specifications


  • Aerospace and defense
  • Wireless communications
  • Radar and wideband signal capture


  • Frequency range: 2.75 GHz to 26.5 GHz (under range to 2.25 GHz)
  • Aux input/switch for signal routing
  • Multiple programmatic interfaces enable easy integration into existing test environments

Performance characteristics

  • 250 MHz bandwidth
  • PXI 1-slot 3U
  • Operating range: -146 dBm to -30 dBm, (nominal) (< 9.5 GHz, -160 dBm)


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.
