The diagram in the "View / Modify Cal Kit Standards" dialog depends on the standard
type for which the dialog was opened. Moreover, it is possible to modify the circuit
model using the buttons in the upper right of the dialog.
Offset Parameters
The entries in the upper part of the "View / Modify Cal Kit Standards" dialog specify the
offset parameters for the transmission lines of the selected calibration standard.
The offset parameters depend on whether the circuit model is defined as "Agilent
Model" (see
Chapter 6.11.2.1, "Cal Connector Types Dialog" , on page 474):
●
In an "Agilent Model", a calibration standard is characterized by its "Delay" (in s),
its characteristic impedance "Z0" (in Ω) and its "Offset Loss" (in GΩ/s).
●
Otherwise the standard is characterized by the R&S ZVR-compatible parameters
"Electrical Length" (in m), "Char. Imp." (in Ω) and "Loss" (in dB/sqrt(GHz)). The loss
is zero and not editable as long as the electrical length is zero.
Both parameter sets are closely related. The "Electrical Length" is proportional to the
"Delay" ; "Z0" corresponds to the "Char. Imp.". Moreover the analyzer converts an Agi-
lent-type "Offset Loss" into a R&S
ZVR-type "Loss" and vice versa using the "Rel. Per-
mittivity εr" for the selected connector type.
See also description of the offset parameters in Chapter 5.5.2.1, "Calibration Standard
Types" , on page 145.
