Restore the
Default Port Assignment
(port 1 / 2 of the analyzer to port 1 / 2 of the cal unit).
This is
important if the automatic detection of the port assignment fails.
•
Start
the necessary calibration sweeps. The calibration is started automatically if automatic port
detection is successful and the cal unit temperature is within the validity range.
•
Abort
an ongoing calibration sweep.
The
Calibration Unit
dialog is closed automatically when all standards have been measured, the system
error correction data has been calculated, and the result is applied to the active channel. The network
analyzer is ready to perform calibrated measurements.
If you accidentally connect a calibration unit which is no suited for R&S ZVL network analyzers
(e.g. one of the cal unit types for R&S ZVA/B analyzers) the analyzer generates an error message,
stating that the characterization of the cal unit is not sufficient.

Cal Kits
•
Opens a dialog to manage the calibration kits in use, add new kits and import or export kits.
Calibration kits
A calibration kit is a set of physical calibration standards for a particular connector type. The magnitude
and phase response of the calibration standards (i.e. their S-parameters) must be known or predictable
within a given frequency range.
The standards are grouped into several types (open, through, match,...) corresponding to the different
input quantities for the analyzer's error models. The standard type also determines the equivalent circuit
model used to describe its properties. The circuit model depends on several parameters that are stored in
the cal kit file associated with the calibration kit.
As an alternative to using circuit models, it is possible to describe the standards by means of S-parameter
tables stored in a file.
The analyzer provides a large number of predefined cal kits but can also import cal kit files and create new
kits:
•
A selection of predefined kits with different types of parameters is available for all connector types.
The parameters of these kits are displayed in the
Add/Modify Standards
dialog, however, it is not
possible to change or delete the kits.
•
Imported and user-defined kits can be changed in the
Calibration Kits
dialog and its various sub-
dialogs.
Calibration kits and connector types are global resources; the parameters are stored independently and
available irrespective of the current setup.
