Generally speaking, if you save data to memory, and then perform a data divide (Date/Memory) for an Insertion Loss trace in S21, would that affect a Phase Trace if that measurement is also placed in S21? Reason I ask is I'm seeing a Phase measurement go out of transition by anywhere from 3-5 pS without the electrical delay being changed at all what so ever. When Data/Memory is off, I do not run into this issue. Just curious to see if anyone has any answers to this. Thank you.
