'Fast' high res data acquisition

H

Harvey Rutt

Guest
I'm looking for a data acquisition system, ideally a card to go in a PC but
I'll take whatever I can find (& pay what I have to!) which is just a bit -
or two - better than I can locate..........

Ideally I want 18 bits at at least 1.5MS/s; a bit faster, another bit would
be nice.

16 bit one or one and a bit MS/s is fairly routine.

I find '24 bit' sigma-delta *devices* claiming 2.5MS/s, but when you read
the data sheet carefully they dont seem quite as good as they claim, at
least when 'flat out', '100dB dynamic range' is only just over 16 bit.

Is there any 'card' out there, or even 'box', Ive missed?

Many thanks.
Seems what I need is at or just beyond what is easily available :-(
