'Fast' high-res data acquisition. |
|
|
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?

Have you looked at GaGe?
http://www.gage-applied.com/
Their standard PCI cards are only listed

to 16 bits and 10 MS/s but they might have something else.
