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 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 following standards:
Standard (Gender)
R (Load)
Electrical Length (Offset)
Open (f, m)
V
0 mm (Delay: 0 s)
Short (f, m)
0
V
0 mm
Offset Short (f, m)
0
V
10 mm
Match (f, m)
Z
0
(reference impedance of the connector type)
0 mm
Sliding Match (f, m)
–
0 mm
Reflect (f, m)
V
0 mm
Through (ff, mm, mf)
–
0 mm
Line (ff, mm, mf)
–

Attenuation (ff, mm , mf)
–
0 mm
Symm. Network (ff, mm, mf)

The following additional parameters are used:
•
Characteristic impedance: Z
0
(reference impedance of the connector type)
•
Loss: 0 dB / sqrt(GHz) (0 G
V
/ 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 and
phase response.
•
To
export
cal kit data, the analyzer uses a specific binary file format *.calkit.
•
Three different
import
file formats are supported: ZVL-specific binary cal kit files (*.calkit), ZVR-
specific binary cal kit files (*.ck), cal kit files in Agilent-specific ASCII formats (*.csv, *.prn; see
notes below).
