Agilent 11974 Series Preselected Millimeter Mixers RF Sections Available in Four Bands from 26.5 to 75 GHz Data Sheet 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. Choose your host spectrum analyzer Agilent 11974 Series preselected millimeter mixers are compatible with Agilent’s 8566B, 8560 Series and E4407B of rugged portables1, 70000 Series modular spectrum analyzers and the E4440A/46A/48A PSA Series1.

Overloading can cause your measurements to be uncalibrated. System amplitude accuracy Millimeter preselection improves system amplitude accuracy by reducing the level of local oscillator (LO) emissions back to the device under test. Option 001 further improves system amplitude accuracy by adding an isolator in front of the input filter. With Option 001, the RF input VSWR is
