Embedding is a function of the S-parameter transformation via integration of some virtual circuit into the real network (See figure below). The functions are applicable for reflection coefficients (S11, S22 etc.) measurement only.
The embedding function allows to mathematically simulate the DUT parameters after adding the fixture circuits.
The embedding function is an inverted de-embedding function.
Embedding
The circuit being integrated should be defined in the data file containing S-parameters of that circuit. The circuit should be described as a 2-port in Touchstone file (extension *.S2P), which contains the S-parameter table: S11, S21, S12, S22 for a number of frequencies.
To open the fixture simulation menu, use the softkeys Analysis > Fixture Simulator on left menu bar. Click on the Embedding field to toggle between the ON/OFF status. Enter the file name of the embedded circuit S-parameters of port by clicking on the S-parameters File field. If S-parameters file is not specified, the field of the function activation will be grayed out.
