The Keysight (Agilent) 11970K Waveguide Harmonic Mixer is a crucial tool for extending the measurement capabilities of spectrum analyzers and other test equipment into the K-band. Operating in the 18 to 26.5 GHz frequency range, this mixer allows users to analyze high-frequency signals by downconverting them to a lower intermediate frequency (IF). This enables accurate and reliable measurements of microwave signals, facilitating tasks such as signal analysis, component testing, and system calibration. Its waveguide interface ensures efficient signal transmission and minimal signal loss, making it suitable for demanding applications in research, development, and production environments.
