Ok, after I did some more looking I figured it out. I didn't figure they
would double the size of the case on a later model.

It is my understanding that yes, you can dump to a memory stick plugged into
the front. There is a port in the back for a printer as well. What scope
do you primarily use?

I kinda wish it had a higher sample rate, but most of what I do is so far
removed from the upper bandwidth of the scope that I really don't think it
should be an issue. Since I've never used a DSO before, I don't have much
"feel" for all these numbers and their significance. I'm figuring it out
though. :-) The comparisons on the TEK site are interesting and
informative, even if they might be tilting things just a wee bit.

It might already be spent. ;-) Have you seen the Intronix LogicPort
analyzer, it looks way cool with built in datastream decoding for SPI, I2C,
serial ASCII and "more". 34 channels, should be more than enough for my
needs.

The Rigol DS1102CD (note the 'D' on the end) has a 16 port logic analyzer.
They want $500 for the option though. :-( The Intronix is less expensive
and more functional (excepting that you could set up complex triggers with
the analyzer built into the scope) Or do you think it would be wiser to go
with the integrated analyzer.

There, I'm all set:

DMM: Extech MM-560
Oscilloscope: Rigol DS1102C
Logic Analyzer: Intronix LogicPort

Now all I need is about $1600 to pay for it all. Paypal donations accepted
;-)
