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 Ω (75 Ω) are
converted into results at arbitrary port impedances.
 Renormalization of the physical port impedances affects e.g. S-parameters and wave quantities in
Power representation.
 Renormalization of the balanced port impedances affects all measured quantities (Trace –
Measure) that the analyzer provides for balanced ports.
The default reference impedance of a physical port is equal to the reference impedance of the connector
type assigned to the port (50 Ω or 75 Ω). It can be defined as a complex value.
