Agilent/Keysight M1970E

The Agilent/Keysight M1970E is a waveguide harmonic mixer that extends signal analyzer capability into the millimeter-wave band. Operating from 60 to 90 GHz, it connects to Keysight X-Series analyzers via WR-12 waveguide and USB, delivering automatic calibration, LO alignment, and real-time conversion loss correction. Maximum conversion loss is 27 dB with ±2.2 dB calibration accuracy. Input SWR is 2.6 nominal.
