Figure 2-6 shows the current waveform of the load: the load’s input current reaches the transient
high level (10A) after 200us duration of rising edge, and remains at 10A for 500us. Then after 200us
duration of falling edge, the input current reaches the transient low level (5A), and remains at 5A for
500us. Repeat it in cycles.

Pulsed Transient Operation
The trigger function is required for pulsed transient operation. When there is no trigger occurs,
the load remains at the transient low level. After a trigger has been received, a pulse with three stages,
namely rising edge, transient high level, and falling edge, will appear, then the load returns to the
transient low level again. The
associated
parameters such as transient low level (LevelL), transient
high level (LevelH), high level time (TimeH), time for rising edge (TimeR), time for falling edge
(TimeF), and pulsed transient mode can be set through transient operation menu or via remote
command (CURRent:LOW <NRf+>, CURRent:HIGH <NRf+>, VOLTage:LOW <NRf+>,
VOLTage:HIGH <NRf+>, RESistance:LOW <NRf+>, RESistance:HIGH <NRf+>,
TRANsient:HTIMe <NRf+>, TRANsient:RTIMe <NRf+>, TRANsient:FTIMe <NRf+>,
TRANsient:MODE PULSe, TRANsient ON | OFF).
In order to get a pulse, an explicit trigger is required. The trigger can be an external trigger signal
received via the TRIG input on
the front panel, pressing the
