Buffer Underflow error(-200016)

[nab-aki]

I'm sorry. I miskate 3 posting. But I could not  know, How to erase these thread.

We control 3Analog Out channel on PCI-6229 using ANSI C.

When we increase Analog Output rate, then Buffer underflow error(-200016) is occurred.

But this upper limit rate is very different between SampleMode(FinitSamples and ContSamples)

   *The result of our evaluation

                         SampleMode Upper                 Rate[Ksample/sec]

                         DAQmx_Val_FiniteSamps          10

                         DAQmx_Val_ContSamps            more than 40

Is this Phenomenon Correct?

Is there any idea for increase upper limit using DAQmx_Val_FiniteSamps of SampleMode.

Sincerely,

[N.Fernando]
