PCIe 6341 is slow with Matlab command 'inputSingleScan'

PCIe 6341 is slow with Matlab command 'inputSingleScan'

‎09-24-2014 08:07 AM

Hi, I have a Multifunction PCIe 6341 DAQ on a 64 bit machine with 64 bit Matlab 2014a. One of the DAQ Toolbox command is called the 'inputSingleScan', this command however is significantly slower than its 32 bit Matlab counterpart 'getSample'. 

 

I like to know if this is an Matlab issue or the DAQ not playing well with Matlab. On my 32 bit machine a DAQ from MCC can achieve 1.4KHz frame rate and this NI DAQ can only achieve 190Hz.

 

I appreciate any input and solutions.
