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.

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:
CHANNEL – [CAL] > "Cal Devices" > "Characterize Cal Unit..."
Background information
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 characteri-
zation data.
