Connecting Counter/Timer Signals

The BNC connection box provides five counter/timer channels that you can use to perform 
the following operations:

• Event counting 

• Up/down  counting 

• Frequency measurement 

• Pulse width/period measurement 

• Edge-to-edge measurement

• Continuous edge-to-edge measurement 

• Pulse output (continuous, one-shot, and repetitive one-shot) 

This section describes how to connect counter/timer signals. Refer to 

page 97

 for more 

information about using the counter/timers. 

Event Counting 

Figure 20

 shows how to connect counter/timer signals to the STP connection box to perform 

an event counting operation on counter/timer 0 using an external gate. 

The counter counts the number of rising edges that occur on the Counter 0 Clock input when 
the Counter 0 Gate signal is in the active state (as specified by software). Refer to 

page 100

 for 

more information.
