Agilent/Keysight M1971V

The Keysight M1971V is a waveguide harmonic mixer that extends X-Series signal analyzer capability into the millimeter-wave spectrum, covering 50 GHz to 75 GHz. This smart mixer combines automatic USB plug-and-play functionality with vector correction data to streamline complex measurement setups. It delivers maximum conversion loss of 27 dB and approximately 1.2 GHz IF bandwidth in normal path mode, while integrated self-calibration and LO amplitude compensation (up to 10 dB loss) eliminate manual tuning across temperature and time variations.
