Data Acquisition on multiple channels

[K.P]

Hi. I would like to ask if it is possible to perform Data Acquisition simultaneouly on multiple channels at different sampling rates and starting and stopping at different timings?

Hi,

This Kind of acquisition is not possible on E series and M series (MIO) and DSA cards i have used ( NI 4472)

Which hardware are you talking about?

I am currently using the DAQPad-6070E (firewire ).

What you ask is definitely not possible on that hardware

However here is a workaround for getting an effect of different sampling rates on different channels

suppose you have three cahnnels and you want to sample one channel at 100k, other at 200 k and third at 300k,

Do this. Sample all three at 300 k and decimate the other two with sutable decimation factors to get the effect of sampling at 200k and 100K

Hope this helps

Regards
