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.
The Calibration Kits dialog contains a series of buttons, each of them opening a dialog:
 Import Kit imports a previously stored cal kit file. The analyzer asks whether to set the imported
calibration kit active.
The modified date of the imported cal kit (the Date of Last Modification in Add / View / Modify
Calibration Kit) is set to the modified date of the imported cal kit file.
 Add Kit combines different standards to form a new calibration kit.
