Even with a wonderful Tek digital scope, looking at irregular relatively

fact, troubleshooting any oddball, unexpected signal can be much harder
with a digital scope than an old analog unit.
I agree with that! Especially with very fast irregular signals which i
can't quite figure out i'll go to the analog scope to see "what's really
there". You'll also sometimes get sampling artefacts with digital scopes
which you need to identify and make the necessary changes, that will
sometimes confuse a novice.
But i wouldn't really want to work analog all the time, the cursors and
easy setup of the digital scope are just too comfortable to miss out on.
If i had to choose one scope... i'd probably cheat and go for one that can
be switched between analog and digital modes ;-)
