PCI-6143 or PCI-6070?

In my application, there are 6 analog input signals of high frequency. The sampling rate I'm looking for is 100ks/s for each signal. I'd use labview 7/7.1 with Window 2000. Which board do you recommend? Thanks very much!

Hello,

In your case, either board would probably serve your purpose. Each of the individual boards has its individual advantages though. The 6070E has a higher overall sampling rate (1.25 MS/s), but this card multiplexes between all of its analog inputs because there is only one analog-to-digital converter on the board. This means that all of the channel readings acquired are not acquired at the exact same instant, but are offset from each other by a small amount of time. The 6070E also has a larger input voltage range at +/- 10V.

The 6143, on the other hand, is a simultaneous sampling DAQ card, meaning that each of the analog inputs has its own analog-to-digital converter associated with it. So the big advantage of the 6143 is that signals can be acqu
ired on multiple channels at the same instant in time.

I hope this helps! Let me know if there is anything I can help with or clarify.
