Setting the Electrical Delay
This feature adds phase delay to a variation in phase versus frequency, therefore it is only applicable for
ratioed inputs.

to compensate for the phase slope at the active marker position. This effectively flattens the phase trace
around the active marker. You can use this to measure the electrical length or deviation from linear
phase.
Additional electrical delay adjustments are required on devices without constant group delay over the
measured frequency span.
