Cal kit file contents
Cal kit files are independent of the current recall set 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 (.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\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 Agilent-
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 ZNC 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 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
ZNC-compatible format.
●
Import the converted file into the R&S ZNC.
*.csv cal kit files: VNA Cal Kit Manager 2.1
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 Manager
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.
