Audio "alignment" is essentially calibration work, and I can't see doing
that
with a scope that I know nothing about.
Have you ever ACTUALLY aligned a receiver?
I was talking about "aligning" audio circuits, e.g. adjusting operating points of various stages, checking response, etc. Not about any sort of RF work.
If I wanted to see a nonlinearity of a stage in an audio power amp, for example, it'd be nice to believe that the scope's vertical system is linear enough, etc. Same goes for step response: hard to do with a scope that may well distort even a perfect square wave.
Gee Kuba,
Anyone who is at all capable of making those kind of measurements
would surely measure the input square wave first. If it looks like
a square wave, then the scope is good enough for the task.
