The fixture modeling proceeds in the following steps:
1. Measure one or more test coupons for the related fixture; see Chapter 5.13.5.2,
"Measure Coupon", on page 629
The tools differ in the available coupon types.
2. Measure the DUT with the fixture; see Chapter 5.13.5.3, "Measure DUT + Test Fix-
ture", on page 631
3. Run the selected tool to calculate the Touchstone files modeling the test fixture;
see Chapter 5.13.5.4, "Save Fixture Model", on page 632.
The calculated sNp file(s) can then be used to deembed the DUT at selected
port(s).
All files generated by actions in this dialog are stored in the directory C:\Users\Public
\Documents\Rohde-Schwarz\Vna\Embedding.
The current implementation assumes symmetrical lead-ins and lead-outs.
