Is It Normal To Have 45 MHz Above Reference?
While scanning monitors on the walls, noticed that the 45MHz spectra was above reference from 0.1-20Hz. (attached is a screenshot, but this was after a few minutes and it began to trend down; currently this spectra is down to the reference for all frequencies.)
This was something which looked odd, so thought I would post a note about it.

Yes, The reference trace has not been updated in a long time.
Most of the time this guy is at the reference. Just happened to catch a few minutes where it was high. Anyway, just something out of the norm I wanted to share.
