Four-port network embedding/de-embedding is a function of S-parameters conversion, using a four-port network as an embedded or de-embedded network. The network is a Touchstone file (with the .S4P extension), containing an S-parameter table of S11, S21, S31, S41, … S44 for a number of frequencies. The embedding and de-embedding operations of this function are mutually exclusive.

To enable/disable the embedding function, use the following softkeys: Analysis > Fixture Simulator > De-Embedding S4P > De-Embedding S4P [ON | OFF] |
|
To select the numbers of ports, connected to the embedded or de-embedded network, use the following softkeys: Analysis > Fixture Simulator > De-Embedding S4P > Ports > [1-2-3-4 | … 4-3-2-1] |
|
|
note |
The set of available port numbers depends on the topology selected. |
|
First you need to specify the name of the *.S4P file for the ntwk1 and/or ntwk2 network. Otherwise the operation softkey will be disabled. To enter the S-parameter file name of the *.S4P embedded or de-embedded circuit for the ntwk1 and/or ntwk2 network, use the following softkeys: Analysis > Fixture Simulator > De-Embedding S4P > File (ntwk1) Analysis > Fixture Simulator > De-Embedding S4P > File (ntwk2) |
|
To select an operation with the ntwk1 and/or ntwk2 network (See topology), use the following softkeys: Analysis > Fixture Simulator > De-Embedding S4P > Type (ntwk1) [None│Embed│De-Embed] Analysis > Fixture Simulator > De-Embedding S4P > Type (ntwk2) [None│Embed│De-Embed] |
|
To display the final circuit based on topology, port numbers, operations and files, use the softkey: Analysis > Fixture Simulator > De-Embedding S4P > Help
