Overview
Network de-embedding is a function for performing measurements, test
port by test port, by removing the characteristics of an arbitrary network
defined by a Touchstone data file. By removing the characteristics of the
cable, test fixtures, etc. between the actual calibration plane and the DUT,
the calibration plane can be correspondingly extended. The network de-
embedding function can be used together with the port extension function.
Port extension and calibration plane extension using network de-
embedding
Using Network De-embedding Function
1. Prepare a two-port Touchstone data file (.s2p format) corresponding
to the network to be removed.
A Touchstone data file is defined for a single
normalized impedance value (real). Thus, when preparing a
Touchstone data file with the 2-port network de-embedding
feature, be sure to specify the same port reference impedance
value (real) to both 2-port network in the file.
2. Press Analysis key, then click Fixture Simulator > De-Embedding.
3. Click Select Port.
