11974A Preselected Millimeter Mixer, 26.5 to 40 GHz

Загрузить техническое описание

The Keysight 11974A mixer is preselected from 26.5 to 40 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.

Keysight 11974A Series preselected millimeter mixers extend the frequency range of the Keysight E4440A/46A/48A PSA Series high-performance spectrum analyzers, the Keysight E4407B ESA E Series portable spectrum analyzer, Keysight 8560E/EC Series portable spectrum analyzers, the Keysight 8566B spectrum analyzer, and the Keysight 70000 Series modular spectrum analyzers.

The 11974A 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
• +25 dBm safe input level
• Optional input isolator improves amplitude accuracy
