Load Parameters
The entries in the lower part of the "View / Modify Cal Kit Standards" dialog specify the
load parameters for a particular calibration standard describing its terminal impedance.
The circuit model for the load consists of capacitance C which is connected in parallel
to an inductance L and a resistance R, both connected in series.
●
R is the constant resistive contribution. It is possible to select:
– "Open" for ∞ Ω (so that the inductance coefficients are irrelevant)
– "Short" for 0 Ω
– "Match" for the reference impedance of the current connector type
– any resistance "R"
●
The fringing capacitance C and the residual inductance L are both assumed to be
frequency-dependent and approximated by the first four terms of the Taylor series
around f = 0 Hz.
See also description of the load parameters for the different standard types in Chap-
ter 9.5.2.1, "Calibration standard types", on page 256.

10.12.2.3 Characterize Cal Unit dialog
The "Characterize Cal Unit" dialog displays the properties of the connected cal units,
provides control elements for characterization file management, and starts the charac-
terization wizard.
Access: [Cal] > "Characterize Cal Unit..."
Background information
Refer to Chapter 9.5.5.3, "Characterization of calibration units", on page 265.
A cal unit characterization can be performed in a frequency sweep. The "Characterize
Cal Unit" dialog is unavailable while a CW Mode or time sweep is active. The analyzer
always uses a fixed source power of -10 dBm to acquire the characterization data.
