*.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.

Calibration Pool
The calibration "Pool" is a collection of correction data sets (cal groups) that the ana-
lyzer stores in a common directory
C:\Users\Public\Documents\Rohde-Schwarz\ZNL\Calibration\Data
. Cal
groups in the pool can be applied to different channels and channel setups. Each cal
group is stored in a separate file named
<CalGroup_name>.cal
. The cal group
name can be changed in the "Calibration Manager" dialog.
One of the available cal groups can be set as "Preset User Cal", i.e. the user correction
data that should be restored after a user-defined preset.
If a new channel is created, the channel calibration of the active channel is also applied
to the new channel. See also
.

Calibration Labels
The following labels in the trace list inform you about the status or type of the current
system error correction.
Table 8-7: Calibration labels (system error correction)
Label
Meaning
Cal
The system error correction is applied without interpolation. This means that a set of
measured correction data is available at each sweep point.
Cal int
The system error correction is applied, however, the correction data for at least one
sweep point is interpolated from the measured values. This means that the channel
settings have been changed so that a current sweep point is different from the cali-
brated sweep points. It is not possible to disable interpolation.
Cal Off
The system error correction is no longer applied (e.g. "User Cal Active" is disabled).
