Overview
This code allows the user to change the source signal for a Two-Signal Edge-Seperation measurement from the internal clock, to a different signal.
Description:
This code was developed for use in detecting a signal (called the 'Source' signal) that arrives after a start signal, but before a second. In this case, the second signal was derived from the first by delaying it with a length of wire to around 200ns. With the start and stop signals configured, a third signal was to be detected. A time measurement wasn't of critical importance, just rising edges of the source signal.
This code was created using the Two-Signal Edge-Separation example code included with LabVIEW 2012. It has been simplified and stripped down to only include Two-Signal Edge-Separation.
Steps to Implement or Execute Code:
To implement this example:
- Define the counter, the new source of the signal and the start and stop edges
- Wire the DAQ based on the wiring configuration of Two-Signal Edge-Separation
- Run the VI
- (Optional) Turn on the Highlight Execution to see the flow of the VI
To execute this example:
- Install the required software.
- Connect the DAQ hardware that supports the Counter features
- Confirm the connection with the MAX with TestPanel
- Open the VI and refer the Implement Steps
