E5071C
Measure the characteristic data of each calibration mixer with the IF filter
used for balanced mixer measurement, using any two ports.
Set the stimulus conditions for the channel you want to calibrate. For the
necessary steps, refer to Setting Stimulus Conditions.
You must also set the external signal source in advance. For the necessary
steps, refer to Setting External Signal Source.
If you characterize a calibration mixer with an IF filter, we
•
recommend that you perform full 4-port calibration in advance,
since it simplifies the evaluation procedures. For detailed
information on full 4-port calibration, see Full 4-Port Calibration.

5. Select Port 1 (1 in menu) to characterize the calibration mixer 1 with
IF filter. In this case, the data are saved to a temporary file
(MIXER_1.s2p).
6. Select Port 2 (1 in menu) to characterize calibration mixer 2 with IF
filter. Here, the data are also saved to a temporary file
(MIXER_2.s2p).
