By default cal kit files are stored in the
C:\Users\Public\Documents\Rohde-Schwarz\Vna\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 Agi-
lent-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
ZNB/ZNBT generates the message "File does not comply with instrument calibra-
tion kit file format". The files must be converted using an R&S
ZVR network analyzer
equipped with a firmware version V3.52 or higher.
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
ZNB/ZNBT-compatible format.
●
Import the converted file into the R&S
ZNB/ZNBT.
*.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
. The decimal separator used by the VNA Cal Kit Man-
ager V2.1 depends on the language version of the Windows
®
operating system: Cal kit
files generated on an English operating system contain dots, the ones generated on a
German system contain commas.
The network analyzer expects the dot as a separator and displays an error message
when a
*.csv
file with commas is loaded. Please install the VNA Cal Kit Manager
V2.1 on an appropriate (e.g. English) Windows
®
version to avoid trouble.
*.prn cal kit files: PNA Cal Kit Editor
The network analyzer can import and process cal kit files created with the PNA Cal Kit
Editor. The files use the extension
*.prn
; the data format is identical to the
*.csv
format.
The decimal separator used by the PNA Cal Kit Editor depends on the language ver-
sion of the Windows
®
operating system: Cal kit files generated on an English operating
system contain dots, the ones generated on a German system contain commas.
The network analyzer expects the dot as a separator and displays an error message
when a
*.prn
file with commas is loaded. Please install the PNA Cal Kit Editor on an
appropriate (e.g. English) Windows
®
version to avoid trouble.
