How do I do high-speed data acquisition with PCI-6023E (55Khz frequency)

[sugus]

Hi all!!
I am starting to get frustated with my program. My goal is to make my board (PCI-6023E) acquire 100 samples of data for 2048 times in frequency of 55Khz.
That means, it will record 2048*100 data = 204800 data in one whole cycle.
The problem is that it takes 3-5 minutes to acquire all the data. The sample timer in the board itself is 200KHz, so it should be no problem to do my acquisition in less than a second.
Is it possible something wrong with my configuration? or is PCI-6023E is too slow to handle this high frequency?

Thanks a lot for the help.... 😃

Hello;

First thing to consider is the number of channels you are reading with the board. The 200KS/s rate is valid for one channel only, if you have n channels, that rate will become 200S/s / n.
I would advise you to run one of the example code programs that are installed on your computer when you install the board driver (NI-DAQ), and set up the parameters you need to achieve that goal. The problem might be either at the Software or at the configuration. If you face the same problem with the example code, we can narrow down the problem to the configuration parameters.
Hope this helps.
