The Calibration Manager dialog contains three main panels:
• Calibration State lists all channels and their current calibration state.
• Calibration Pool contains a list of all stored correction data sets.
• Calibration Properties displays the basic channel settings and the, the System Error Correction
Data, and the Power Correction Data available for the channel selection in the Calibration State
panel.
Calibration states
One of the following calibration states is assigned to each of the channels listed in the Cal State table:
• No Callibration 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.
• 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
Channel.(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.
