TRAN ON ；Enables the transient operation
CURR:LOW 1 ；Sets a value to low level
CURR:HIGH 5 ；Sets a value to high level
TRAN:HTIME 200ms ；Sets a value to high level time
TRAN:RTIME 10us ；Sets a value to time for rising edge

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 200Ωand 500Ω; 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.
