Are you saying that you get different deviation at different
frequencies? That would be an indication of a frequency-
response that was not flat (i.e. broken). Assuming that
your test source is "flat".
As for the actual deviation level, it would depend on the
level of your test source, and the practice of that particular
cable operator, I would think. Their head-end technician
should know what the standard is, whether documented or
in his head.
