The Keysight M1970E is a waveguide harmonic mixer that extends compatible signal analyzers into the millimeter-wave spectrum, enabling measurements from 60 GHz to 90 GHz. This un-preselected mixer integrates automatic calibration and alignment features to streamline test setup and enhance measurement accuracy. Connection via USB provides both power and data transfer, enabling real-time conversion loss correction and automatic local oscillator amplitude compensation for cable losses up to 3 meters or 10 dB. The M1970E automatically detects its identity when connected to a compatible X-series analyzer, self-configuring frequency range and LO harmonic settings while performing automatic alignment at startup.

– Typical Applications
Millimeter-wave signal analysis and characterization in the 60–90 GHz band using Keysight X-series signal analyzers.
– Compatibility & Integration
The M1970E interfaces with Keysight N9040B UXA, N9030A PXA, N9020A MXA, and N9010A EXA signal analyzers. All X-series analyzers require Option EXM for harmonic mixer compatibility. RF input accepts WR-12 waveguide; IF and LO signals use SMA (female) connectors. Power and configuration data transfer via USB.
