Hi,Damian Marek
Thanks a lot! I have read that post and now I can understand the definations of Relative Power and Path Monitor.I also understand why it is less than 1 at the input.In my case,the starting field is Mode so I think the “Power in path “ graph should start from the value closing to 1.00 (maybe 0.9 or 0.8).But actually it’s only 0.32 . I just think it’s too little. Is that reasonable?
