Calibration states
One of the following calibration states is assigned to each of the channels listed in the Cal State table:
 No Calibration No specific channel correction data is available. The factory system error
correction is used. This is the default situation when a new setup is created (File – New).
 Channel Cal A system error correction and/or power correction with channel-specific correction
data is active. A new calibration of the channel affects the channel-specific correction data only;
no cal group file will be overwritten..
 Uses <CalGroup> A system error correction with one of the correction data sets (cal groups)
stored in the cal pool is active. A new calibration of the channel replaces the correction data in the
cal pool and may affect several channels, see below.
The channel calibration of the active channel is also applied to a new channel created via Add Channel +
Trace. Corr Off indicates that the system error correction for the channel has been deactivated using
Correction Off.
If a new calibration is performed for a channel assigned to a cal group (marked as Uses <CalGroup>),
the correction data overwrites the cal group data, so the new calibration will affect all channels assigned to
the cal group. The network analyzer generates a notice message "New calibration will overwrite cal pool!"
when opening the first dialog (Select Physical Port Connectors) of the calibration wizard.
The buttons in the upper half of the dialog are used to modify the Cal Pool and apply pool data to
channels:
 Add -> copies the correction data of the selected channel to the cal pool, generating a new pool
member (cal group).
 Replace -> overwrites a cal group with new correction data.
 <- Apply assigns the selected cal group to the selected channel.
 <- Apply to 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 <Ch<n>>, 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 so 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.
