Keep in mind that a DSO is substantially a different

simply a "more modern replacement for an analog oscilloscope". Many
people, some of whom really should know better, assume this because
that's the way things have generally worked with technology, with
digital stuff being perceived as "new" and anything analog perceived
as "old" or otherwise passe'. This is not completely so with DSOs.
They have significant limitations that one MUST be aware of in order
to use them effectively. If you don't know what you're doing with a
DSO, it will give you incorrect information.
Early DSOs certainly were not suitable replacements for analog scopes.
Modern DSOs, except perhaps for the very low-end ones, seem to me to be
suitable to replace analog scopes for nearly all uses. Perhaps there are
some limitations that I haven't encountered?
