incorrect measurement rate when running DAQ653xTst

Post by Bruce »

Hi all,

We are trying to collect data from the Active Two from within a Visual C++ application. As a starting point, we have used Roger Carff's sample project, DAQ653xTst, a simple console app which initializes, streams, un-initializes, and displays data from the Active Two hardware. It appears to work well, except that the number of collected frames is far less than what we would expect. For example, if the hardware speedmode is set to 4, we would expect to collect 20,480 data frames over a 10 second period. But using DAQ653xTst, we only collect about 500 frames over that period... even when the frame-decimation value is set to 1. Has anyone else had this experience? If so, do you know why the actual collection rate is so low, and how to correct it? Thank you for any help you can give.
