Hi
I am experiencing problems with a 8563E spectrum analyzer. Upon startup, or whenever the unit is preset it shows a block of green above the noise floor, making the unit unuseable. The only way to rid the unit of this is to turn on the video averaging, but I would like to know why it is doing this.
See uploaded picture for what it looks like
Thanks in advance

It looks like your positive peak detector on the interface board has gone bad. If you go into the menu and select detectors and switch between sample negative peak and positive peak you will see the same effect on the positive peak selection .
