sample rate

[yettaboom]

I have a question about the sample rate: i have acquire 4 channels and i use the vi "acquire waveforms.vi". For example if I set the sample rate to 50 ksample/s , the daq acquire each channel with 50 ksample/s or 50k/4 ? I use a DAQ with a max sample rate of 200 ksample/s.

Thanks

I'm sure you have a question but it would be nice if you actually asked it.

Perhaps the following Data Acquisition Sampling Terminology here may help you understand your problem

Specifically
"Sample/Sampling rate (scan rate)
The rate at which one sample per channel is acquired; the rate at which the sample (scan) clock is set. Note that the maximum sampling rate specification for our E Series data acquisition boards refers to the maximum rate at which a single channel can be acquired. For example, the PCI-6071E is capable of a 1.25 MS/s sampling rate. This may consist of 1.25 MS/s on one channel or 250 kS/s on five channels."

You would acquire each channel at 50 ksamples/sec.
