Counter Output Applications; Simple Pulse Generation - National Instruments cRIO-904 Series User Manual

The figure below shows an example of a sample clocked buffered two-signal separation
measurement.

Counter Value
Note If an active edge on the Gate and an active edge on the Aux does not occur
between sample clocks, an overrun error occurs.
For information about connecting counter signals, refer to the
section.

Counter Output Applications

The following sections list the various counter output applications available on the cRIO
controller:
•

Simple Pulse Generation

• Pulse Train Generation
• Frequency Generation
• Frequency Division
• Pulse Generation for ETS
Simple Pulse Generation
Refer to the following sections for more information about the cRIO controller simple pulse
generation options:
• Single Pulse Generation
• Single Pulse Generation with Start Trigger
Single Pulse Generation
The counter can output a single pulse. The pulse appears on the Counter n Internal Output
signal of the counter.
You can specify a delay from when the counter is armed to the beginning of the pulse. The
delay is measured in terms of a number of active edges of the Source input.
