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

input 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.
