error 10843 - underflow error - PCI 6025E - when outputing two waveforms simultaneously

[Evan A Young]

I am experiencing the above error while trying to output two waveforms simultaneously. What is the fastest update rate that I could possibly use? I would like to get it to 10kS/s or even faster, but it seems to freeze the outputs once you try to get above 9kS/s.

I am developing in LabView 6i.
Thanks

Please post your code for us to look at.

I have done over 1MS/s using the 6110.

Hello,

Upto 10KS/s is the specification for the card you are using as mentioned in the data sheets and it is system dependent.

So most likely you will get 10KS/s or less update rate depending on the speed of your system.
