MODE CV Sets the mode
TRAN ON Enables the transient operation
VOLT:LOW 1 Sets a value to low level
VOLT:HIGH 5 Sets a value to high level
TRAN:LTIME 400 ms Sets a value to low level time
TRAN:HTIME 200 ms Sets a value to high level time
TRAN:RTIME 10 ms Sets a value to time for rising edge

4.7.2 Pulsed Transient Operation
Example 1: Assume that the load is in external triggering mode, set the load current value to periodically switch between 1 A and 5 A;
set the time for rising edge (TimeR) to10 ms; set high level time (TimeH) to 200 ms; set time for falling edge (TimeF) to 10 ms; the load
is in pulsed transient operation, and a trigger occurs at this time.
