WebApr 18, 2016 · We will need one for Analog Input from the potentiometer ( A) and one for producing a Pulse Width Modulation signal ( B) on the DIO0 line. Notice how the names used in LabVIEW match the ones we've indicated in Figure 3. Once we read in the potentiometer value, we also need to scale it ( B ).

Figure 8 illustrates how to create a pretriggered application in LabVIEW by specifying the desired number of pretrigger samples in the DAQmx Reference Trigger VI.
WebPulse-width measurements measure the time between either a rising and a falling edge, or a falling and a rising edge. The formula for pulse width is as follows: Pulse width (in seconds) = Count / Counter Timebase Rate where Count is the number of ticks of the counter timebase that elapsed during one pulse width of the input signal being measured. WebJun 13, 2024 · A simple way of measuring time using the timing functions in LabVIEW is to use the Get Date/Time in Seconds or Tick Count function to grab the time at the start of a process, and then call it again later, subtracting your old value from it to see how much time has passed.

WebDec 19, 2024 · High Pulse Width Measurement: The amount of time that the signal spends above its mean value. This is the average value for all the pulses in a waveform that have a rising edge, when Whole Trace is selected, or related to the rulers if one of the other options is used. So the readings you are seeing look to be correct.
