The pure and precise MXG

Whether you’re pushing for more dynamic range or an optimized receiver rejection, the MXG delivers what you need: phase noise, non-harmonics, output power, and more. Take your devices and designs to the limit with the MXG.

Generate the signals you need with outstanding hardware performance

  • Test radar receiver sensitivity or characterize ADC or mixer signal-to-noise ratio, with unmatched phase noise and spurious performance
  • Drive receiver front-ends for out-of-band rejection with industry-leading output power
  • Simulate multi-channel composite analog modulation with integrated multifunction generator
  • Create variable RADAR PRI and pulse width with integrated pulse train generator

Maximize resources with low cost of ownership

  • Increase uptime with high mean time between failures (MTBF) based on first- generation MXG track record
  • Minimize downtime and expenses with self-maintenance strategy and low-cost repairs
