7.2.2 Voltage step transient
Voltage step transients will cause the output voltage to go to the value
specified in the Goto V field starting at the phase angle specified in the
phase ø field for a duration specified in the Delay (s) field. The delay value
can range from 1 ms to 9999 seconds. At the end of the delay period, the
output value will still be at the Goto V value so there is no need to specify a
Final V value.
The delay value is specifically useful if the step transient is part of a list of
linked registers. In this case, the delay value will determine how long the
value remains at the Goto V value before the link is made to the next register
in the sequence. At that time, whatever transient is in this register may
change the voltage to a new value.
The illustration shown here reflects an example of a typical V Step
transient. The required row in the data entry screen for this transient would
be as shown below. In this case, register 0 was used to store the transient
information.
