Programming output transients

Up to now the ac source has been programmed with the transient system in Fixed mode. The following examples briefly describe the transient system’s Step, Pulse, and List modes, which require the application of a trigger to implement the transient mode.

NOTE: For the examples that follow, press Shift Output, scroll to *RST and press Enter to reset the unit prior to each example. Also press Enter to enter or activate each selection.

Pulse transients transition to a new output level upon receipt of a trigger and return to the original level after a specified time, repeating this action by the number of times specified by the count. When these commands are sent, two output pulses step the voltage amplitude from its previous setting to 90 V rms upon receipt of a trigger. At the end of the specified period (multiplied by the count), the voltage returns to its original level.

List transients generate complex output sequences. When these commands are sent, the voltage amplitude is sequentially stepped to three levels upon receipt of a trigger, and then returns to the original voltage level. The output remains at each list step for .5 seconds. The values inside the brackets ([ ]) are the list index references. Use Clear Entry to clear a list.
