Testing Pulse Output
To verify that the board can perform a pulse output operation, do the following:
1.
Connect a scope to counter/timer 0 on the DT3000 Series board. Refer to
page 53
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 DT3000 Series board from the Board list box.
4.
Select either
Continuous
to output a continuous pulse stream or
One Shot
to output one
pulse.
5.
Select either
Low-to-high
to output a rising-edge pulse (the high portion of the total pulse
output period is the active portion of the signal) or
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.
Enter a percentage or use the slider to select a percentage for the pulse width. The pulse
width determines the duty cycle of the pulse.
7.
Click
Start
to generate the pulse(s).
The application displays the results both in text and graphical form.
8.
Click
Stop
to stop a continuous pulse output operation. One-shot pulse output operations
stop automatically.
