The buttons in the upper half of the dialog are used to modify the Cal Pool and apply pool data to
channels:
•
Copy >> copies the correction data (Channel Cal) of the selected channel to the cal pool,
generating a new pool member (cal group).
•
Apply assigns the selected cal group to the selected channel.
•
Apply All assigns the selected cal group to all channels in the Cal State table.
•
Resolve Pool Link deletes the assignment between the selected channel (Ch<n>: Uses
<CalGroup_name>) and the cal group. The correction data from the cal group
<CalGroup_name> is used as a channel calibration for <Ch1> , the Calibration State list
displays Ch<n>: Channel Cal.
•
Delete From Pool deletes the selected cal group.
You can apply any correction data set (cal group) from the Cal Pool to several channels, which
may belong to different setups. When doing make sure that the port configuration of the
channels (connectors, state, ...) and the cal group are compatible.
You can also use a cal group stored in the Cal Pool to define a channel-specific calibration.
Apply the cal group to the channel and click Resolve Pool Link.

Calibration 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.
