The Keysight (Agilent) M1970V is a waveguide harmonic mixer that extends spectrum analyzer and signal analyzer frequency coverage into the millimeter-wave region. It downconverts high-frequency RF signals to intermediate frequencies compatible with X-Series analyzers, enabling measurement capability in frequency bands otherwise inaccessible through direct analysis. The M1970V employs USB plug-and-play connectivity with integrated smart features that automate mixer detection, LO alignment, amplitude correction, and calibration routines—eliminating manual configuration overhead and improving overall system DANL and TOI performance.

– Compatibility & Integration
The M1970V integrates with Keysight X-Series signal analyzers including the N9030A PXA, N9020A MXA, and N9010A EXA. Special applications may be supported with specific analyzer options such as PXA Option CR3. The mixer operates across the analyzer’s native IF frequency range without requiring external configuration or calibration files.
