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 a special value
("Open" for
∞
Ω so that the inductance coefficients are irrelevant, "Short" for 0 Ω,
Match for the reference impedance of the current connector type) or set any resist-
ance 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.

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.

Background information
Refer to
Chapter 4.5.5.3, "Characterization of Calibration Units"
A cal unit characterization can be performed in a frequency sweep. The "Characterize
Cal Unit" dialog is unavailable while a power, CW Mode, or time sweep is active. The
analyzer always uses a fixed source power of –10 dBm to acquire the characterization
data.
