the macro (1 in Figure 4-73).

NOTE If failure occurs when reading the data file for the calibration mixer with IF filter, the

characterization may have done by using only one port instead of using two ports.

Step 9. Select the measurement port as shown in Figure 4-73 (2 in Figure 4-73) and then connect a

THRU between the IF ports of the calibration mixers to correct the phase difference of the

LO signals for the calibration mixers with IF filters.

Step 10. Pressing the

Execute (3 in Figure 4-73) button executes a phase error correction and

overwrites the results on the original data file.

NOTE You cannot run the Execute function when selecting the measurement port if the data file

of the calibration mixer with IF filter (*.s2p) has not been set for the network removal

function of the fixture simulator.

NOTE The phase error correction data reflects the phase difference of the LO signals for the phase

information of the calibration mixer’s data file, which is registered in any two ports.

Step 11. Press the

Close button (4 in Figure 4-73) to exit macro.
