panel.
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 (Nwa-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.
•
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
New Add Chan
+ Trace
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 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:
•
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.
