This article was put together over 10 years ago to advise individuals mitigating interference that their spectrum analyzers can be in saturation without them knowing this is occurring. Most manufacturers have different methods for letting users know when their test unit is in saturation; however, this does not apply for lower power levels. It takes a significant amount of addition power (after saturation begins) before a test unit indicates this on the screen. It is still very true today. As mitigation is getting more and more complex, I am beginning to see more damaged units.
