[sdiy] which oscilloscope?

[Ray Wilson]

Garge sales can be a source of scopes. I got my first half decent scope, a
40 MHz Hewlett Packard solid state for $20.00 and it still works.  I went
for one of Circuit Specialist's sales and got a brand new 40MHz with two
pretty nice probes for $239.00. The deal also threw in a half decent DVM for
free. I'll let you know if it dies on me but so far its pretty good.

  Those Web-tronics oscilloscopes are not dependable.  I speak from
experience.  My first one crapped out just under the warranty period.  The
replacement they sent went out in another year, apparently a bad tube this
time.  I doubt this scope ever met its stated specifications, for instance,
the display always dimmed at higher sweep rates.



  I settled for a used Tektronix scope off ebay.  You take your chances here
too.  Anything affordable is generally an older model with risk of failure.
But at least these name brand units (Tektronix, HP, LeCroy, Philips) are
better built.

  Hi James



  I would suggest at least (20MHz Dual Trace) this or up (40MHz, 60MHz,
etc...).

  Or... you could also go with a PC based scope. Something like this:

    So, what are some of the recommendations for someone getting into DIY
and wanting/needing a scope. I guess my general feel with equipment is that
I'd rather buy once and be done even if it means laying out more cash and
having some growing pains at first as I'm flooded with more options then I
may need. I've poked around on ebay and there seems some pretty reasonable
deals but I really don't know what I'm looking at. Recommendations?
