Trigger Operation
Trigger operation is commonly used in transient test function (Con, Pul, and Tog) and
List function. The load supports three triggering modes to allow synchronization with
other DUT. They are Tran trigger, Bus trigger, and DIGIO trigger. Before enabling the
trigger function, please select a trigger type first.

Transient Trigger (TRAN)
In the local operation mode, press the TRAN key on the front panel, and then
one trigger operation is executed. At this time, "TRAN" at the top of the main
interface is highlighted and active.

Bus Trigger (BUS)
When the load receives the remote triggering command (:TRIG:IMM) via the
interface, the load will perform one trigger operation.

Digital I/O Trigger (DIGIO)
The digital I/O interface on the rear panel of the load can be used to receive the
external trigger signal. When the external trigger is in effect, the load will
perform one trigger operation once a low pulse is received over the trigger
terminal. The trigger output signal over the digital I/O interface can be used to
trigger an external device, such as a digital oscilloscope, an electronic load, and
other products.
Slew Rate and Minimum Transition Time
Slew rate is defined as the change in current, resistance, or voltage over time. It is
the speed of transition from one setting to another. You can set the actual transition
time from one setting to another by changing the slew rate. Figure 2-46 shows the
relationship between the set slew rate and the transition time. The slew rate
determines the minimum transition time between two settings. When the slew rate is
set to be a maximum value, it indicates that the transition time between the two
settings is the smallest.
Tip
Turning the short circuit on does not affect the set values of the current
parameters, and the load will return to the previously set state when the short
circuit is turned off.
