Hi all dears;

                    some tell me is it sure that PCI-6025E druver 6.9.2 version have support DMA i m in confusion bercause my system clock slows down at high data acquisition rate. Its one reason is that at high rate my system cpu has to transfer the data so due to this may system clock slows down. Please some one surely tell me does this board support DMA.

                                                  thanks

Hi,

The PCI-6025E and the NI-DAQ 6.9.2 support DMA transfer.  However, I strongly recommend that you upgrade to the DAQmx driver.   NI-DAQmx can increase application performance over Traditional DAQ (Legacy) in many applications because of driver architecture improvements.

Here are a couple of links with more information about DAQmx:

Here are some other things that you can do to improve performance with your current application:
close other applications that are running
acquire the data before performing any analysis or modifications
