How do I plot phase differences

I am trying to plot the phase difference between two ports, and I can't quite figure out how to do it. I am using Genesys ver 7.52
No one else has this question

There is a few ways that you can take the difference of phase between 2 ports. One method is to open up your global equations window and create an equation for the difference of phase. For example, an equation that looks like:
DIFF_PHASE = abs(Linear1.Sch1.ANG[S11] - Linear1.Sch1.ANG[S21])
In this equation you are taking the absolute value of the difference of the two measurements. Here is an explanation of each part
"Just a variable name."
"absolute value of a number"
"Linear1 is the name of your Linear Analysis.
Sch1 is the name of the schematic that you
are using and ANG[S11] is the measurement."
When you want to graph it, right-click on outputs and select a graph type. For the "Default Simulation/Data or Equations" select Equations. Then for your measurement, use =DIFF_PHASE
There are other ways to create this, but I find that this way provides the most reusability.
