NI 9219 Fast Sampling Rate

Highlighted

Hi NI Community,

 

I have a NI 9219 DAQ recording resistance at very fast rate (20S/s) but the module cannot keep up the sampling rate. I used the sample program for resistance and added a few arrays to record the time and data on the table. Apparently the module can only record a change in value for every 5/10 of a second. How do I improve my structure so that the program records the data for every 1/10 of a second or 1/100 of a second based on the sampling rate input? Would the hardware be capable in achieving this task?

Can't look at your code now, but have you seen this?   Looks like you may need to configure the device away from its default limit of 2 Hz sampling.

Hi, one thing I noticed, maybe it's just a default value, but the sample rate on the front panel is set to 1000 and the max sample rate of the NI-9219 is 100.
