Fixture Modeling
We create and apply a fixture model for single-ended deembedding at ports 1 and 2
using the ISD tool.

Perform a full two-port calibration at ports 1 and 2
For an example, see
Measure the test coupon
We are using a single-ended (2-port) "Symmetric 2x Thru" coupon (balanced). Connect
it to ports 1 and 2.
