Testing Pulse Output
To verify that the module can perform a pulse output operation, do the following:
1. Connect a scope to counter/timer 0 on the DT9812, DT9813, or DT9814 Series module.
Refer to
page 42 for an example of how to connect a scope (a pulse output) to
counter/timer 0.
Note: The Quick DataAcq application works only with counter/timer 0.
2. In the Quick DataAcq application, choose Pulse Generator from the Control menu.
3. Select the appropriate DT9812, DT9813, or DT9814 Series module from the Board list box.
4. Select Continuous to output a continuous pulse stream.
5. Select High-to-low to output a falling-edge pulse (the low portion of the total pulse
output period is the active portion of the signal).
6. Click Start to generate the pulse(s).
The application displays the results both in text and graphical form.
7. Click Stop to stop a continuous pulse output operation.
