Unexpected step in measurement #101

Please see the video that shows the unexpected "step" at 8 seconds: https://www.youtube.com/watch?v=1ohqsk5OO6s

My question: is this 'normal' behavior or something that needs a fix? I do not see the behavior on another SA I own.

The step you see if the AGC of the high input reducing gain and thus increasing the noise floor after the strong signal. Suggest to add 20dB more attenuation
