4.7.3 Toggled Transient Operation
Example 1: Assume that the load is in external triggering mode, set the load resistance value to
periodically switch between 200
Ω
and 500
Ω
; set the time for rising edge (TimeR) to 10ms; set time
for falling edge (TimeF) to 10ms; the load is in toggled transient operation, and a trigger occurs at this
time.
