is it possible to get a ABOUT speed information of the NI-DAQ driver ? I have a stepping through application - means :
( 1 step then 100 acquisitions next step ) * 1000 steps
With my P200 and a PCI Mio16E1 I need about 3-4 seconds to get the 100 000pts. But as long we know the PCI 16E1 is much faster ! Therefore I loose speed somewhere.
Anybody who can give me a hint ?
For stepping i use the async. mode by generating a waveform. The waveform is loaded in a 1000 steps big buffer and for synchronizing I start each output update by the general purpose timer. With the same timer tick I start a 5 channel scan to acqu. the 100 data and re-program the time a.s.o. I can program the timer down to a µsec. but it won't run faster than with 100µsecs. Where i my mistake ?
Does the programming of the timer need so much time ? (you need to do it every step !)
PS: The same programm with AO_write instead of wfm-out is even slower !
