Hi Max,
Thank you very much for your recommendation. However, the name of resource I set is the same as your suggestion as following:
DAQ::1
but it sill did not work.
I attached some srceenshots below:
Thanks again!

Hey,
Try reducing the number of records fetch per cycle or reduce the sampling rate and see if the error still persists. Also try running the example VI for continous acq using NI-Scope this might help you see too.
Good luck

Hi,
Thanks for the ideas...turns out our cards are damaged (I suspect we might have overdriven the inputs). I put a known good 1khz 5Vpp square wave in, ran the Soft Front Panel application and it only captured some of the waveforms, then dropped to some negative voltage reading. So our frequency measurement still worked sometimes when there were enough midpoint crossings. But our peak to peak voltage measurement never read correctly, because of the drop to a negative voltage (would give us a faulty high Vpkpk reading).
thanks for your help.
