The Keysight N5186A MXG is a multichannel vector signal generator engineered for wireless communications, aerospace, and defense test applications. It delivers complex signal generation with support for advanced modulation schemes including MIMO, beamforming, and multiplexing. The instrument configures from 1 to 4 unique output channels in a compact 2U form factor, minimizing rack space while reducing external connections. Custom DAC ASICs employing direct digital synthesis (DDS) produce signals with minimized distortion across demanding component and receiver test scenarios.
