6.4 Programming Output Transients
Output transients are used to:
• Synchronize output changes with a particular phase of the voltage waveform.
• Synchronize output changes with internal or external trigger signals.
• Simulate surge, sag, and dropout conditions with precise control of duration and phase.
• Create complex, multi-level sequences of output changes.
• Create output changes that have rapid or precise timing requirements.
The following power source functions are subject to transient control:
• AC output voltage
• DC output voltage
• Frequency
• Start phase angle
• AC/DC voltage slew rate
• Frequency slew rate
The following transient modes can be generated:
Step generates a single triggered output change.
Pulse generates an output change which returns to its original state after some time
period.
List generates a sequence of output changes, each with an associated dwell time
or paced by triggers.
Fixed turns off the transient functions, which means that only the IMMediate values
are used as the data source for a particular function.
After a *RST or Device Clear command, all functions are set to FIXed, which turns off the transient
functions.
