Amplitude and Phase Tracking
Using the same measurement setup as in “Phase or Group Delay Measurements,” you can
determine how well two mixers track each other in terms of amplitude and phase.
1. Repeat steps 1 through 8 of the previous “Group Delay Measurements” section with the
following exception:

3. Replace the calibration mixer with the mixer under test.
The resulting trace should represent the amplitude and phase tracking of the two mixers.
