extension can eliminate only electrical delay (phase shift) for each single-
ended port. Loss or mismatch cannot be eliminated by this function.
Functions for Single-Ended (Unbalanced) Port
The following three functions are applied to single-ended ports (unbalanced
ports). Balance-unbalance conversion can additionally be applied to single-
ended ports.
Network de-embedding
A function that uses software to remove an arbitrary network (50 ohm
system) defined by a two-port Touchstone data file from each test port
(single-ended) and to extend the calibration plane. This makes it possible
to remove networks that create error elements between the calibration
plane and the DUT, thereby enabling a more realistic evaluation of the
DUT.
For the setup procedure of the network de-embedding function, see
Extending the Calibration Plane Using Network De-embedding.
Port reference impedance conversion
A function that uses software to convert an S-parameter measured with a
50 ohm port reference impedance into a value measured with an arbitrary
impedance.
For the setup procedure of port reference impedance conversion, see
Converting the Port Impedance of the Measurement Result.
Matching circuit embedding
A function for converting an original measurement result into a
characteristic determined under the condition of inserting a matching
circuit between the DUT and the test port (single-ended). The matching
circuit to be inserted is either selected from the five predetermined circuit
models or provided by a designated arbitrary circuit defined in a two-port
Touchstone file.
For the setup procedure used for matching circuit embedding, see
Determining Characteristics After Adding a Matching Circuit.
4-port network embedding/de-embedding
This is a feature to embed (in terms of numerical calculation) your desired
network that you have defined in a 4-port Touchstone data file into
measurement results or to de-embed it from them.
When you use this as de-embedding, the embedded matching circuit and a
part of networks in the DUT are removed.
For information on how to operate this function, refer to Obtaining
Characteristics After Embedding/De-embedding 4-port Network.
