How to measure group delay of a 2 port network using Microwave Office?

hi everyone
would you please help me measuring the group delay of a two port network using microwave office?
your fast answer will help me too much
thanks in advance

Just take the derivative of the phase-vs-frequency characteristic (linear frequency scale!).

yes I know the meaning of group delay.But im looking for some method to determine the value of GD directly using microwave office software.for example like measuring S11 im this software

Actually group delay is a two-port measurement, and cannot derivative from S11.
MWO have a direct option for measuring group delay.
Choose rectangular graph, choose measurement, linear, group delay.
