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.
1. Press Macro Setup key.
2. Click Load & Project.
3. Specify "D:\ Agilent\ MixerCharacterization.vba" for the file name in the
Open dialog box and then press the Open button.
4. Press Macro Run to run the macro.
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).
o For detailed information on characterizing the calibration
mixer, see Characterizing procedure for calibration mixer
(with IF filter).
7. Click (Optional) Balanced Mixer (2 in menu).
