Do the line sweeps before any PIM testing

    Your PIM Corner is an excellent idea.:)

    It is important to note that PIM measurements are not significant unless they are accompanied by complete line sweeps beforehand.

    PIM requires a low system loss and a good return loss to be able to perform to an acceptable standard.

    Poor return loss reflects some of the PIM test signals back into the test equipment causing some signal cancellation that can report a false positive.
