read ADC functions at 1000Hz? (7344)

[whatsthis4]

Is it possible to read data from the ADC's on the UMI(and store it) at 1000Hz. I read somewhere on the forum saying that high speed capture is only good up to a certain rate. Obviously reading in a loop with the waitms = 1ms would not work. Any suggestions?

Thanks

The ADC is in can only do software timing. So a loop with 1 Ms timer is the fastest it can go with software timing. The 7344 can only do software controlled acquisition. To do 1000hz you would want to use hardware timing with a National Instruments Data Acquisition Board.

I just want to add that high speed capturing (HSC)has nothing to do with analog data acquisition. In HSC mode the board captures the position of an axis whenever a trigger occurrs on the trigger input.
