When you post pictures of a signal to the list, please post one image
per posting, or you risk the post either bouncing, or list
subscribers not getting the images as there are too many attachments
(one picture per post, but you can make 15 posts if you like with no problem).
Also, please, please, please remember to show us or tell us what the
setting are on your spectrum analyzer or scope, for example, what is
the dispersion (span) or what we are looking at, what IF BW were you
using, what Video BW, what was the refresh rate?
Also, try to measure and define the bandwidth of what we are looking
at, then set your IFBW to approximately that BW (as close as you can
get), and show some shots of the screen in zero span mode so that we
can see the signal in the time domain.
Also, zoom out more, and show us more of the spectrum, or at least go
up and down a few screens so we get an idea of what else is on the airwaves.
On initial impression it looks like leakage from a broadband network,
but you need to provide a ton of additional information in the signals.
