Hello,
I have a cDAQ 9185 chassis with a NI 9237 module. The manual for the 9237 states that the lowest possible acquisition rate is… “down to 1.613 kS/s depending on the value of n. When using an external timebase with a frequency other than 12.8 MHz, the NI-9237 has a different set of data rates.” I need to be able to sample at 1,000 S/s,
How can I access other timebases which I assume in my case is provided by the cDAQ 9185? If I try to select an external timebase, for example, if I try to create a NI-DAQmx task for a load cell, when selecting Advanced timing tab, and changing the Sample clock type to external, any timebase or sample clock gives me an error. I also select “Let NI-DAQ Choose” the timing engine, as I don’t know the meaning of selecting a specific one.A similar message pops-up if I try to do this from a .vi.
I thought of sampling at 2kS/s and decimate the results, but is seems inelegant.
Thanks everyone.
