Getting error -200802 and -1931, don't know how to fix it?

[woochles]

Hi. I'm a bit new to Labview, and I'm trying to run a noise generation program that a now graduated student wrote. I'm getting two errors, but I don't know how to fix them or even what is really wrong. Any help would be awesome. I'm not even sure where to change the settings that are recommended.

Error -200802 occurred at Gaussian Noise.vi:Instance:1:1

Possible reason(s):

Write cannot be performed when the task is not started, the auto start input to DAQmx Write is false, the Sample Timing Type is something other than On Demand, and the output buffer size is zero.

Call DAQmx Start before DAQmx Write, set auto start to true, modify the Sample Timing Type, or change the output buffer size.

Error -1931 occurred at SVFA Power Spectrum (1 Ch).vi:6
Possible reason(s):

Sound & Vibration:  The number of samples should be greater than 0.

Try posting in the Dynamic Signal Acquisition forum as well...they handle more Sound and Vibration Suite questions...

woochles,

I agree with gaving that the DSA forums may be a better location for this inquiry. However, you should also include the following information:

-Your code

-What hardware you are using

-Versions of the software you are using (LabVIEW, Drivers, etc...)

This information should help us answer your question.

Best,
