Notes from a discussion with colleagues, cleaned up a bit.
Mixing products inside the analyser create images and multiple responses; check with a different span and RBW. Internally generated harmonics at high input level are a classic false positive. An over-driven front end compresses and produces spurs that look like real emissions. Use an attenuator and verify the spur moves or not with input level.
What does your setup look like?
