Hi everyone,I'm curious about the SA option in PNA-X.It can do specrtum measurements without hardware preselector.In Keysight's help files it says it has software-based preselector function which can eliminate image signals.And in the SA setup there is a image reject menu with six options.I'm not sure how does it works.Does anyone know about the algorithm?And another question is the confidence level.Does this function eliminate all of erroueous signals?Can I trust all of the signals displayed on the screen?Thank you.
