Questions

 

How is interference caused by PIM different than the interference detected in the SA Interference Analysis?

Answer

 

Testing performed in Interference Analysis is for detecting interference at specific frequencies coming from other wireless sources over the air. PIM Detection testing is to detect wideband interference caused locally at the antenna (i.e. poor cabling, mismatched impedance etc..) PIM testing should done with the radio configured for full power.
