What is interesting is that all of your traces appear to be identical except
for the vertical scale factor, which suggests that the ringing you are seeing,
which is much improved from your earlier plots, is still a little bit of a
problem. I am going to guess that , as Bob pointed out, is probably due to a
reflection problem in the input side of the attenuator. Could be the attenuator
input impedance is not a good match to the source, or could be a cable
impedance issue.
I hope that suggests some things you could try experimentally and educationally
to sort it out.
One trick is to move the attenuator to the other end of the cable (i.e.
at the output of the device) and then run the coax to your 50 ohm scope
input, and see what it looks like.
