The different steps for deembedding and embedding are carried out in the following order:
This means that the real networks are removed before virtual networks are added. For a a single
balanced port with all (de-)embedding networks enabled, the 4 (de-)embedding steps are carried out in
the following order:
1. Initial situation: DUT embedded in 2-port and 4-port networks (only 1 port shown)
2. 2-port deembedding
3. 4-port deembedding
4. 4-port embedding
5. 2-port embedding
Reference Impedances...
Changes the reference impedances of the analyzer ports. This is often referred to as renormalization of
port impedances. Renormalization means that the measurement results measured at 50 (75 ) are
converted into results at arbitrary port impedance.
