DAQmx write delay for long data

[cgermer]

Hi, can anyone help me?

I'm trying to write a long PWM data to DAQ NI-USB-6002 analog output, but I'm having problems on time delay. 

I want to output a sequence of 5 PWM with different duty cycles at the exactly time I press RUN button. However, it is taking almost 4 seconds to the data be output. I realize that the data is very long (each PWM has 4 seconds length and is sampling at 5kHz), but I really need control of what time data starts to be output. What can I do?

Thanks

Hi cgermer,

I didn't understand your last post. Did you solve your problem? If so, what was the solution you found? If not, please let me know so I can help you.

Best Regards.

Hi Felipe,

Actually I didn't have to do anything. It has a delay, but it is ok. The problem before was that I forgot that I initialize the sequence with zeros!

Sorry about that!
