The analyzer combines the data in an appropriate manner:
●
The Match results are used up to the lower edge of the specified frequency range
of the Sliding Match (Min Freq).
●
The Sliding Match results are used for frequencies above the Min Freq. In general,
the Sliding Match provides better results than the Match within its specified fre-
quency range.

Cal kit Files
Calibration kit files can be used to store the parameters of a particular calibration kit, to
reload 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 recall set and contain the following informa-
tion:
●
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 (.s<n>p file) that are necessary to
determine its magnitude and phase response.
By default cal kit files are stored in the
C:\Users\Public\Documents\Rohde-Schwarz\ZNA\Calibration
directory.
●
To
export
cal kit data, the analyzer uses a specific binary file format
*.calkit
.
●
Three different
import
file formats are supported: R&S
ZVA-specific binary cal kit
files (
*.calkit
), R&S
ZVR-specific binary cal kit files (
*.ck
), cal kit files in Key-
sight-specific ASCII formats (
*.csv
,
*.prn
).
Importing older R&S
ZVR cal kit files
On loading some older R&S
ZVR-specific
*.ck
files, e.g. the R&S
ZV-Z23 cal kit file,
the R&S
ZNA generates the message "File does not comply with instrument calibration
kit file format". The files must be converted using an R&S
ZVR network analyzer equip-
ped with a firmware version V3.52 or later.
Proceed as follows:
●
On the R&S
ZVR, press "CAL > CAL KITS > MODIFY KITS > INSTALL NEW KIT"
to import the
*.ck
file.
●
Press "CREATE INST FILE" in the same submenu to export the
*.ck
file in a
R&S
ZNA-compatible format.
●
Import the converted file into the R&S
ZNA.
*.csv cal kit files: VNA Cal Kit Manager V2.1
The VNA Cal Kit Manager is a free, Windows
®
-based software tool intended to import,
edit, and export
*.csv
cal kit files. The software is available for download at
