There's a wide variation in new and used analog scope prices, and
perhaps the usually 'you get what you pay for' applies
How does a new entry level 2 ch 20MHz $400 compare to a higher BW $700
model? How much $$ goes for increased BW?
I use older, seemingly good working order, low BW scopes for
automotive work. Adjusting everything as best and as much as possible
(to my intermediate knowledge), using different X10 probes, various
probe lead routings, I can only see the saturation injector waveform
(goes to near ground to activate the injector) @ 2ms Time/DIV (the
injector PW spec is [coincidentally?) 2.2ms, which is what I see w/the
trace at just over 1 grid. If I sweep faster (which I want to do) or
slower, I get ga ga. With most of the other auto components, I have no
problem at faster time bases
Would a low-current inductive probe/clamp help (understanding a
different waveform sample must be referenced)?
Would a higher end scope, presumably with better (and/or more
durable?) internal components, have a more flexible trigger, or
'sensitivity' in the generic sense? Or how might higher end scopes
perform better (better CRT? etc.)Other thoughts or suggestions?
Thank you,
Lance
