How to get 1kHz sampling rate?

Hi guys,
 
using the following VI, I'm unable to write 1k samples/second in my measurem
ent file, it ends up with little more than one sample/second. Changing the t
ime delay in the while-loop to a lower value helps nothing, I get less data 
points then. To be more exa
ctly, I get more points but most of them contain zero values and are unusabl
e.
I specifically talk about the 3th and 4th flat frame, the first one is allri
ght because it has different requirements.
 
Thanks in advance

Hi ReBoot, have you tried with setting the "number of samples" count for tho
se "DAQmx Read" operations? Usually you shouldn't need the "Wait" function a
s the DAQmxRead will have to wait for the number of samples...

So I'd have to get the user input for the run time and multiply that by 1000
 to get the number of samples? Will try that tommorow (I have LV only at wor
k and I'm at home now).

Using the Read VI itself to time the measurement (numberofsamples=samplerate
*desiredtime) is good, thanks!

Where do I rate?

Hi ReBoot, you may rate once you have a minimum of 50 posts to the forum...
