I have been considering buying a scope. What bandwidth, channels, etc. is
needed?

I am extremely interested in this.

Well most scopes are 100 MHZ and two channels.
They still run about $1500 new.

You can some times find used bargains on e-bay.

This is a classic. Four channel and 350 MHZ

A bit over kill for single chip computer use.

I have something like this one. Works great for single chip computer use.

Make sure you get probes in the bargain as they can run into real
money.

Hey guys, this is the digital age!  :)

Check out http://www.bitscope.com for USB and Ethernet connected
PC-based oscilloscopes.  Let me know if you get one - I want to know how
they *actually* perform.  I plan on getting one instead of a full-blown
bench-top oscilloscope.

That looks great Vince. The logic analyzer ought to come in real handy if
you are doing anything with single chippers. The portable aspects
are real important when traveling around as I usually carry a note
book computer anyway. I have two scopes already but I am really tempted.

Vince, thanks for the pointer. Just what I was looking for, I think.

I just ordered the bitscope 310 with/USB. I also ordered the logic probe.
Delivery should be in ~2 weeks (priority handling - air was $25 more and
only saves ~7 days). Didn't realize it was made Down Under. That's OK.
Aussies are OK. We had an Aussie unit with us in Korea (7th Inf. Div.).
Swell fellows for the most part.

I like the fact that the software runs under either Linux or Windoze.

Will post my impressions of it when it arrives.

Paul, if things work out timing wise, I could bring it to Mark's hangar. You
and Mark could get a look at it then. We might even do some good! :)

Good I'll pack my extra Tracy computer and we can use that pressure
sensor to get a handle on the problem. Probably about Friday or Sat
after the start of OSH. I can stop in Denver on my way home.
