DAQmx Base maximum AO write rate

Hi,

 

we are running LabVIEW 2015 on OpenSUSE, which means that we have acces only to DAQmx Base. We want to generate a waveform and write it using the DAQ card NI-6289.

 

However, it seems that the DAQmx Base is limited to write rates of about 8000 samples/s. When trying to write faster, an error occurs stating that DAQms Base does not use buffer and so it can not write faster. Is there a workaround around this to generate samples much faster?

 

If you want to replicate this error, use any of the DAQmx Base AO examples and set the number of samples few hundred higher than 8000 per second.

 

Best Regards

 

Petr

If DAQmx has that limitation regardless of the output hardware, you may need to try a different approach like using an external arb.
