Description
For the first time, preselected signal analysis is available to 75 GHz. With preselection, you can quickly and easily characterize all signals of interest. No images or multiples are displayed to confuse the measurement. Time consuming signal-identification routines are eliminated.
Figure 1 shows how true signals can be obscured by displayed multiples and images in an unpreselected system. Figure 2 shows how only the
true signals are displayed when an Agilent Technologies 11974 Series preselected millimeter mixer is used in making the measurement.
Whether your millimeter-frequency application is component or system testing, signal surveillance or EMI measurements, your software
development and verification time will be reduced and your measurement times will be decreased. Simply place a marker on a signal—all responses are real—and perform a preselector peak. The analyzer then displays the amplitude and frequency of the signal. No time is lost creating and running signal identification routines, which used to be required to separate true responses from multiples and images.
Each 11974 Series preselected millimeter mixer is characterized for conversion loss versus frequency. Calibration accuracy ranges from 1 dB at 26.5 GHz to 2 dB at 75 GHz. Just enter the conversion loss data into your host spectrum analyzer and then make amplitude-calibrated measurements

Description
11974V preselected mixer will be discontinued, last day to order is May 31, 2015
The Keysight 11974V mixer is preselected from 50 to 75 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 11974 Series preselected millimeter mixers extend the frequency range of the Keysight E4440A/46A/48A 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 11974V is not compatible with the N9030A PXA signal analyzer.
