The list shows the available connector types with their name ("Conn Type"), polarity
("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" pro-
vides 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 sexless 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
ter 4.4.3.9, "View / Modify Cal Kit Standards Dialog"
●
The calculation of the (default) reference impedances for balanced ports (see
●
The calculation of impedance and admittance parameters (see
chapter 3.3.3, "Admittance Parameters"
Remote command:
Line Type / Rel. Permittivity / Cutoff Frequency f
c
"Line Type" describes the wave propagation mode (offset model) in the transmission lines
of the standards associated with the connector type.
●
If the calibration kit standards contain lines with transverse electric propagation mode
(TEM, e.g. coax cables), then the "Relative Permittivity ε
r
" of the dielectric can be
