4.7 Transient function

The transient test allows switching between two different load values.A common
application is to test the dynamic characteristics of DC source.
There are three different types of transient operation: continuous, pulse, toggled.

4.7.1 Continuous mode

In continuous transient operation, the load iscontinuously switched between two load
values.An example is shown in the following figure:

4.7.2 Pulse mode

In pulse operatrion,the load operates at the A value that has been entered until a trigger

timing value.Then the load switches back to the A value and stays there until another
trigger is received.
