5.2 Transient test operation

Transient operation enables the DC load to periodically switch between two levels.
To edit a transient test file, related parameters need to be set: A level, B level, time width
(only in pulse mode), frequency, duty and running mode (Continuous/Pulse/Toggled). If
in CC dynamic mode, user can set current rising and falling slope additionally.
Following is an example to illustrate the three transient operations.
