Just so--what's to prevent you from aquiring a
used
'scope and
learning how to use it? I'm still using an old Tek
465 that I've had
for a long time that does most of what I need in a
piece of test
equipment. I've also got a logic analyzer, but it
rarely sees the
light of day.
There is a certain level of tooling required for
most fields. I
suppose you could work on your car with nothing more
than a pair of
gas pliers and a hammer, but doing things right
requires the right
tools.
Absolutely nothing. Except finding the time and
desire. And I wouldn't need to learn how to use it,
though a brushing up would be in order. Still, my
instincts would be to try a li'l chip swapping rather
then get all hot-and-bothered by a thorough diagnosis.
Besides, as the gnattering off-list respondent has
said, I'm not really all that bright, so a proper
piece of test equipment probably wouldn't do a whole
lot of good :<
I want one of those color HP DSOs I used for a bit in
the late 80's. They were $30Gs back then I think.
Anyone have a clue as to the model #?
Yet I can only wonder what *could* be used to scope
out problems on the uP systems of today. You need at
the very least 2x the sampling rate to effectively
analyze a waveform. I cannot image what an 8ghz scope
would go for.
