Hi Mike
I see them¡. but I guess I would question why you are worried about it. That spike will have no meaningful impact on any measurement you make.
I would be interested to know though how the spike you are showing reacts to a slight change in Span¡. which will move the bin boundaries. But in reality those spikes do not impact significant measurements.

Hi Warren
Good thought about the bin boundaries, worth further investigation.
I'm definitely seeing a 600MHz spike as well at times though, see attached
photo. (Apologies for the poor quality.) Any idea for the mechanism that
generates those? I'm struggling to think of one aside from some weird
aliasing effect.
