From the Transient menu, the desired transient step type can be selected. Based on the user’s
choice, the relevant transient type sub menu will be shown. The START/ED

Voltage sweeps cause the output voltage to change from the
present value to a user specified end value at a specified rate of
change. A voltage step on the other hand is an instantaneous
change in output voltage. The new value will be held for the

This transient type combines the previous two types in
single step. The effect is that of changing the output voltage
and frequency simultaneously.
