My application requires the AD2 to measure a ac pulse and store the data in a CSV file that can later be plotted. The sensor that needs to be measured by the AD2 is attached to a Robot that moves it to various locations in 3 dimensions (X,Y,Z) The robot is controlled by a Rpi4 and is programmed to stop at thousands of locations per experiment. The Robot has Two Programs, One that positions the sensor at the desired location and stops waiting for a signal to go to next location. The second tells the instrument to take a measurement and saves the results including the X,Y,Z location and the measured data. When the measurement is complete and the data saved the second program tells the Robot to go to the next location and repeat. So far we have been taking DC measurements from a digital voltmeter which communicates via the serial port. Now we need to capture a pulse and record the waveform in a CSV file for later analysis. We have been successful using the Waveforms program to display the pulse and desire a way to handshake to tell the Robot to continue. With the digital output we could tell when the measurement was complete and signal the Robot to continue. Is there a way to initiate a capture of a single pulse or series of N pulses to a file and somehow signal when it is finished writing the file? Any ideas welcome as we have thousands of these measurements to perform? Thanks
