Timer 2: Pulse width timer
•
Set the delay attribute to an appropriate pulse width (see the following figure).
•
Set the stimulus input to Timer 1's event ID (the start of each pulse is the start of the pulse
period).
•
Set the count equal to 1 so that only one pulse is issued per period.
SMU A
•
Set the source stimulus input to Timer 1's event ID so that the source action starts when the
period starts.
•
Set the end pulse action to
smua.SOURCE_IDLE
so that the output is returned to the idle level
after the pulse completes.
•
Set the end pulse stimulus input to Timer 2's event ID so that the end pulse action executes when
the pulse width timer expires.
•
Set the trigger count equal to 1.
•
Set the arm count equal to the total number of pulses to output.
The following figure shows the trigger setup for this example.
