Also be aware that even though the analyzer may not be reporting an error (IF overload, etc) that does not mean that other devices upstream, such as a preamp or transient limiter, are not in saturation. A linearity check, if performed, should be done upstream of devices such as these.

Any decent receiver in overload does not show a measurement value but blinks, reports an error condition (IEEE-bus) or has a bright red blinking error led or beeper. I have never been able to reproduce this phenomenon with a spectrum analyzer without reported error condition. (and certainly not with all signals -spurious included- meeting limit lines, and make me conclude a compliant result.)
