 Disable User Characterization Warnings in the Calibration Unit dialog.
 Start the characterization wizard (Start Characterization).
If the calibration unit supports SD cards and an SD Card is inserted into the calibration unit's SD card slot,
characterizations stored on the SD Card are marked with (SD Card) after their name in the
Characterization Data selection list
A cal unit characterization can be performed in a frequency sweep. Start Characterization is
unavailable while a power, CW Mode, or time sweep is active. The analyzer always uses a fixed source
power of –10 dBm to acquire the characterization data.

Characterization Wizard
The Characterization Wizard consists of a series of dialogs which perform a new characterization of the
R&S calibration unit. It is opened from the Characterize Cal Unit dialog. Characterization involves the
following steps:
1. Select the calibration type
The calibration unit supports different calibration types. Depending on the desired calibration type,
a simpler or more complicated characterization procedure is required. The NWA calibration that
you have to perform before connecting the calibration unit also depends on the desired calibration
type:
 If Full One Port and Full Two Port calibrations are needed, a simple characterization
procedure involving only one-port measurements is sufficient. The calibrated ports are
connected one after another. A Full One Port or Full Two Port calibration of the analyzer
at all ports used for the characterization is recommended.
 If a One Path Two Port calibration is needed in addition, the characterization procedure
also involves two-port measurements. The calibrated ports are all connected at the same
time. A Full N Port calibration of the analyzer (for N calibrated ports), for different
connector types and adapters preferably UOSM, is required.
2. Select the characterized cal unit ports
3. Perform the necessary characterization sweeps, depending on the selected calibration type (step
1)
4. Save the characterization data
Characterization data are saved in ASCII format with a specified file name and comment. The
default file extension is *.calkit; the files are written to a subdirectory of C:\Program
Files\Rohde&Schwarz\Network Analyzer\Calibration (or any other specified directory). The
network analyzer automatically creates a file header containing the following information:
 Current date and time
 Characterized ports, together with their connector types and gender
 Operating temperature of the calibration unit
 Sweep parameters: sweep type, number of points, frequency range
If the calibration unit supports SD cards and an SD Card is inserted into the calibration unit's SD
card slot a check box Store on SD Card is displayed left of the filename entry field. If checked, on
pressing Save and finish the characterization is written to the SD Card.
