No, I am not sure what DAQ device to select.
What are your requirements?
Which voltage range is to be measured? (This is part of your homework!)
Which resolution and accuracy do you need? (This is a question popping up on each measurement task, so consider that also part of your homework/learning process!)
Which samplerates are needed? (This depends on the signals you want to acquire…)
Some other requirements like connection to your computer? (USB, PCI(e), Ethernet, …)
After answering those questions you can look into the hardware selector on NI's website and choose some suitable products…
Good Morning GerdW,
Thank you for the support that you have been providing to me so far.
I am not very smart guy with learning problems.
I am giving up on this. Once a again thanks for everything.
I wish you all the best.
