The list shows the available connector types with their name ("Conn. Type") and polar-
ity ("Sexless"). The remaining columns in the list are described below.
Storing connector type settings
Calibration kits and connector types are global resources; the parameters are stored
independently and available for all recall sets. The connector type settings are always
stored together with the associated calibration kit parameters. The
Calibration Kits Dia-
log provides buttons to export and import cal kit and connector settings.
After assigning a calibration kit to a user-defined connector type, you can still change
its name, offset model and reference impedance. Switching between sexed and sex-
less will delete all kits assigned to the connector type.
Char. Imp.
The characteristic impedance or reference impedance ("Char. Imp.") Z
0
for the connec-
tors is a critical value that has an impact on various parameter conversions. Z
0
enters
into:
●
The calculation of the S-parameters for the calibration standards associated with
the connector type, provided that they are derived from a circuit model (see
"View /
Modify Cal Kit Standards Dialog" on page 325).
●
The calculation of the (default) reference impedances for balanced ports (see "Ref-
erence Impedance Tab" on page 443).
●
The calculation of impedance and admittance parameters (see Chapter 4.3.2,
"Impedance Parameters" , on page 113 and Chapter 4.3.3, "Admittance Parame-
ters" , on page 116).
