I am looking to use the DAQ MX read subvi as a 2D DBL to output data from several analog inputs on my device. I wanted to see if there is a way to set the sampling rate when I am measuring multiple samples. I would like to set the sampling rate to 1000Hz if possible. Essentially I will be using this to filter incoming data from pressure sensors as the incoming signal is rather noisy.
Of course you can set the sample rate. That's what the DAQmx Timing function is for. Have you looked at any of the shipping examples? One of the simpler ones is called Cont Acq&Graph Voltage-Int Clk.vi.
If you use a waveform data type, then many of the functions will automatically get the sample rate.
