Hi Dave

The 465 is a nice Scope! however, not a DSO at all, and I think that
Digital storage is a requirement for capture data from Rs232, It would be
useful to see if the voltage changes are right, but to see
what data is going on, how many bits, and stuff like that, you need a
digital storage.

You need Digital Storage for that, I have at home the TDS 220 and is a
amazing machine, I can see almost everything, and I think that it worth
every cent I spend on it, but , I buy it because I work at home.  if you
intend to use it for hobby maybe it's a little expensive for that :-)

I think that If you want an Oscilloscope for digital use, and hobby only,
you can use a
computer based scope, they are far more cheaper (yet not as good as a
TDS-210) and
is good for digital signals.

an even cheaper way for digital analisys are parallel port "software" logic
analyzer.

There is one at: www.xs4all.nl/~jwasys/old/diy2.html

the program is called : digitrace_win95.zip

I downloaded the software (the only necessary thing), but don't tested yet,
it uses the
parallel port directly as digital inputs directly.
Does not have too much storage 32K samples only, but It can be enough for
Rs232 capture.

see you

Leandro
