Vector-Mixer Calibration
Characterizing calibration mixer (with IF filter) for balance mixer
measurement
The VBA macro (Vector Mixer Characterization) provided with the E5070B/E5071B
allows you to characterize the calibration mixer (with IF filter) to be used for the balanced
mixer measurement. The characterizing procedures of the calibration mixer with IF filter
used for balance mixer measurement are basically the same as those used for normal mixer
measurement; however, two characteristic data of the calibration mixer with IF filter are
required for balanced mixer measurement, as shown in Figure 4-71.
Connect the target calibration mixer (with IF filter) to the port of the network analyzer on
which calibration has been performed and then connect the OPEN, SHORT and LOAD
standards to the end of the IF filter to start reflection measurement and characterization.
For a balanced mixers, the phase difference of the LO signals between the calibration
mixers with IF filter will remain as an error, since each calibration mixer with IF filter is
characterized independently. Therefore, you must calibrate the phase difference between
the two characterized calibration mixers with IF filters.

How to execute characterization
1. Characterizing Calibration Mixer (with IF filter)
Measure the characteristic data of each calibration mixer with the IF filter used for
balanced mixer measurement, using any two ports.
