Reset Port Assignments
Restores the identity between original and assigned port number.
Save Settings in Recall Set
The "Select Ports" dialog preserves the selected and assigned port numbers. By
default (unchecked), these settings are global, i.e. they are identical for each recall set
and are not affected by a [Preset]. However you can also choose to preserve specific
settings for the current recall set (checked).
Note however that the settings are not persisted unless the "Select Ports" dialog is
closed using "OK".

Linearity Deviation Tab
Allows you to set up and activate a linearity deviation view for the active trace.
Instead of the trace itself, the linearity deviation view displays the deviation of the trace
values from a linear function of the current sweep variable sv:
LinDev_Tr(sv) = Tr(sv) – (
"Constant" and "Slope" can either be specified or obtained from a linear regression of
the original trace. The latter makes sense if you want to verify linearity but currently do
not care if the trace values are close to a particular target line.
"Linearity Deviation" is only available for cartesian trace formats.
On
Activates/deactivates the linearity deviation calculation using the current
and
values. When activated, the trace statistics info field is shown and populated
with the following (additional) lines:
●
Lin Deviation On
●
Slope <value><Y-scale unit (per X scale unit)>
●
Constant <value> <Y-scale unit>
