USB-6363 and Matlab

[ImranKalhoro]

Hello,

I am using the NI USB-6363 Multifunction DAQ and have noticed that each DAQ write operation in Matlab takes 200 ms (with the the DAQ rate set to 10000 Hz). Is this limitation related to the DAQ itself, or is it related to the computer I am using the DAQ with?

Thank you,

Imran

There are other possible reasons:

• You have multiple programs running at the same time and your PC does not have enough CPU resources to process your program.
• Your USB-6363 is connected via a USB hub and the bandwidth is shared

I would recommend testing with different programming methods, e.g. Python, C, C#, LabVIEW to isolate the cause.

Hi,

Thanks for your reply! 

1. I am meaning to upgrade the PC so perhaps that will make it faster. But this implies that the problem is not inherent to the DAQ itself, correct?

2. The USB-6363 is connected directly to the computer via direct USB cable and no USB hub is involved. 

I will try your suggestion of using other programming methods to interface with the DAQ and see if it is an issue around Matlab.

Please let me know if there is other things I should try or look into. Much appreciated!

Thanks again,

Imran
