with frequency. The offset slope begins at 0 Hz. and continues to the stop
frequency. The offset value at the start frequency is then calculated from 0
Hz.

Electrical Delay

Electrical delay is a mathematical function that simulates a variable length of
lossless transmission line. Use the electrical delay feature to compensate for
the linear phase shift through a device and view only the deviation from linear
phase of the device.
You can set the electrical delay independently for each measurement trace. To
apply an electrical delay to all measurement traces, use Port Extensions. Learn

Phase Offset

Phase formate is available only with S11 measurements.
Phase offset mathematically adjusts the phase measurement by a specified
amount, up to 360°. Use this feature in the following ways:
Improve the d isplay of a phase measurement. This is similar to the way you
would change the reference level in an amplitude measurement. Change the
phase response to center or align the response on the screen.
