Dummy parameters (labelled Dummy Kit) describe an idealized calibration kit for each
connector type.
Make sure to use universal or individual parameter sets if you need to obtain high-precision
results. The precision of the calibration kit parameters determine the accuracy of the system error
correction and of the measurements. The calibration wizard displays a warning if you use a typical or
dummy 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.
Dummy kit parameters
All dummy kits contain the following idealized standards:
Standard (Gender) R (Load) Electrical Length (Offset)
Open (f, m) 0 mm (Delay: 0 s)
Short (f, m)
0
0 mm
Offset Short (f, m)
0
10 mm
Match (f, m) Z
0
(reference impedance of the connector type) 0 mm
Sliding Match (f, m) – 0 mm
Reflect (f, m) 0 mm
Through (ff, mm, mf) – 0 mm
Line (ff, mm, mf) – 10 mm
Attenuation (ff, mm , mf) – 0 mm
Symm. Network (ff, mm,
mf)
– 0 mm
The following additional parameters are used:
•
Characteristic impedance: Z
0
(reference impedance of the connector type)
•
Loss: 0 dB / sqrt(GHz) (0 G / s)
•
All inductance and capacitance parameters are set to zero.
Cal Kit Files
Calibration kit files can be used to store the parameters of a particular calibration kit, to reuse the data
and to exchange calibration kits from one network analyzer to another.
Cal kit file contents
Cal kit files are independent of the current setup and contain the following information:
•
Name and label of the calibration kit
•
Connector type including all connector type parameters (name, polarity, offset model, reference
impedance)
•
Type, gender and label of all standards in the kit together with the circuit model parameters
(offsets, load) or S-parameter tables (.snp file) that are necessary to determine its magnitude
