Timed acquisition

Hi pr,

Zitat:do you mean a Daqmx Task that generates a digital edge for the acquisition?
In my case, the digital event source is an external machine (via NI9361).

No: setup a task using an external (digital) signal as start trigger.
Did you examine the example VIs coming with LabVIEW? There are a lot examples for DAQmx…

Zitat:Maybe I need to set for the acquisition channel to read a specific amount of samples as you said (Please could you check the capture below).

Well, you want to acquire a fixed amount of data, so you can read a fixed amount of samples…

Zitat:for the 2nd option, do you mean that I need to read the first saples and then delete them ?! and read the next samples ?

Either do two reads. Or just one read operation and use ArraySubset afterwards…
