Characterizing calibration mixer (with IF filter) for balance mixer

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.

Characteristics evaluation of calibration mixer (with IF filter) for balance mixer

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.
