Hi,
I am looking for a DAQ to analyze data from 3 different channels. The sampling rate is about 100 KS/s (for each one), and the signal level is between 2mV to 2V. I found NI USB-6281 may work for us, but noticed that the DAQ does not have the simultaneous sampling function.
In theory, we need to process data from different channels at the same time. But as a matter of fact, our signal is expected to be a square wave with the frequency of 10 KHz. In other words, we plan to use 10 points in each cycle to describe the entire square wave at 10 KHz. I wonder whether the simultaneous sampling function is necessary or not in this case, if the data starting and ending moments are available for post process.
We have no experience on working with DAQ. Can anyone with experience make some comments? If necessary, I can explain more about my project.
Thanks.
