Cal kit parameter types
The analyzer uses three types of parameters to describe the calibration standards. The
parameter type is the same for all standards in a kit and therefore appended to the kit
name:
●
Universal
parameters (no suffix) describe calibration kit models with highly stand-
ardized components so that the parameters are valid for all calibration kits of the
model.
●
Typical
parameters (suffix "typical") approximately describe a calibration kit model.
To correct for deviations between the standards, each kit of the model is individu-
ally measured and delivered with an additional, kit-specific parameter set. There-
fore each typical parameter set "<kit_name> typical" is complemented by an addi-
tional parameter set "<kit_name>" containing optimized parameters for an individ-
ual kit.
●
Ideal
parameters (suffix "Ideal Kit") describe an idealized calibration kit for each
connector type; see below.
Make sure to use universal or individual parameter sets if you need to obtain high-pre-
cision results. The precision of the calibration kit parameters determines the accuracy
of the system error correction and of the measurements. The R&S
ZNA displays a
warning if you use a typical or ideal parameter set to calibrate a channel.
Calibration kits can be obtained as network analyzer accessories; refer to the data
sheet for the relevant ordering information. The name of all parameter sets is equal to
the name of the corresponding calibration kit model.
Ideal parameters
All ideal kits contain the standards listed below.
