4.7.4 Pulse Transients
Pulse transients let you program the output to a specified value for a predetermined amount of
time. At the end of the Pulse transient, the output voltage returns to its previous value.
Parameters required to set up a Pulse transient include the pulse count, pulse period, and pu
duty cycle. An example of a Pulse transient is shown in Figure 4-10. In this case, the count is 4,
the pulse period is 16.6 ms or 60 Hz and the duty cycle is 33%.
