Now we have an interesting situation. While we can measure the per-
formance at the connector— which is the calibration plane— what we
really want to know is how our device performs (Figure 8-21).
You can consider the device embedded in the fixture and can measure
the S-Parameters of the fixture with the device installed.
The most elementary situation is a system in which the test fixture is
electrically ideal or transparent. In this case the solution is sim-
ple—merely move the reference plane out to the device (Figure 8-22).
