I have to capture sound pressure from a microphone using one channel of USB-4431 and frequency (counter input) from a mass flow meter using one channel of USB-6341. Both the devices are connected to a laptop. I wish to get the output data at a sampling frequency of 6000 Hz (0.000167 s time step). The sound pressure output is in 0.000167 time step whereas, the frequency result is in 3.4 s. Could any one please suggest a method to get both the results in the same time step of 0.000167 (6000 Hz). Also the start time for the first measurement has to be same for both the devices. The LabVIEW code and the result are attached.
Many thanks
