two sample rates on PCIe6259 using NIDAQmx

[jimmek]

I have 8 sensors. For six, a sampling rate of 10 KHz is more than adequate. For two, a sampling rate of 60 KHz is desired. In the past, before NIDAQmx, I used two DAQ boards to simplify the programming. With NIDAQmx and the smarter DAQ boards and software which removes the user further away from low level programming, is it now possible to have two sample rates corresponding to two channel ranges 0-1 and 2-7?  Are there any NIDAQmx sample codes? 

Also, is there NIDAQmx sample codes for the GPCTR's, specifically for a frequency/counter divider? I have seen some for NIDAQ.

Hi Jim,

With the PCIe-6259, you can still only have one sample rate. I would just sample all you your channels at 60 kHz, which will still be below the 1 MS/s scanning sample rate of the PCIe-6259.  If you are looking for LabVIEW examples, you can find them in the Example Finder located at Help >> Find Examples.  Once the Example Finder opens, make sure the Browse tab is in top left is selected.  To find DAQmx examples, double click Hardware Input and Output >> DAQmx >> Analog Measurements (to find analog measurement examples) or Counter Measurements (to find examples using the counters).
