In PSP(PSS, Shooting meyhod) analysis there is one option called "Choose Harmonics" under "Select PORTS" menu.
I am NOT able to understand what is its role.
What is its use when you are already specifying the frequency Range.
I went through several Spectre docs but unfortuantely could not find/understand its exact use.
Can anybody please tell what is its role and why it is needed in PSP
