Calibration Overview
Operating Manual 1145.1084.12 – 30 54
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 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
are available irrespective of the current setup.
Calibration Types
The analyzer provides a wide range of calibration types for one, two or more ports. The calibration types
differ in the number and types of standards used, the error terms, i.e. the type of systematic errors
corrected and the general accuracy. The following table gives an overview.
