11974Q Preselected Millimeter Mixer, 33 GHz to 50 GHz

Загрузить техническое описание

The Keysight 11974Q mixer is preselected from 33 to 50 GHz to eliminate the need for signal identification. The Keysight 11974Q mixer is preselected from 33 to 50 GHz to eliminate the need for signal identification. Preselection reduces mixer overload from broadband signals and reduces the interaction of local oscillator harmonics with the device under test. True signals can be quickly located, and software development for automated measurements is greatly simplified. The 11974Q features advanced barium-ferrite technology and comes with a stand-alone power supply. It is especially useful for broadband millimeter signal analysis, electromagnetic interference measurements, and unattended monitoring of millimeter signals.

Keysight 11974 Series preselected millimeter mixers extend the frequency range of the Keysight E4440A/46A PSA Series high-peformance spectrum analyzers, the Keysight E4407B ESA-E Series portable spectrum analyzer, Keysight 8560 E-Series portable spectrum analyzers, the Keysight 8566B spectrum analyzer, and the Keysight 70000 series modular spectrum analyzers.

The 11974Q is not compatible with the N9030A PXA signal analyzer.

• Preselection eliminates the need for signal identification and improves dynamic range
• Supplied with calibration data
• No bias required
