6.Press until you access the voltage list. This specifies the amplitude of each output point during its corresponding dwell period. The first voltage list point (0) appears in the display. On the Entry keypad, press 1 6 0 and Enter.

7.Pressing the Enter key automatically advances to the step in the list. Enter the following values for voltage list points 1 through 5: 0, 120, 0, 80, 0. Press Enter to enter each value. When you finish, you will be at point 6, which is the end of the list.

Note: Press Shift ￿Index or Shift Index to access and edit any list point.

8.Press until you access the step command. Check that it is at the default mode (AUTO). This lets a single trigger run your list for the specified count.

9.Press Output On/Off to enable the output. The Dis annunciator will go off.

10.Press Trigger Control and Enter to initiate the transient trigger sequence.

11.Press Shift Trigger. This sends the ac source an immediate trigger to generate the four output pulses. The output returns to the immediate value at the end of the list.

Note: To clear a list, press Clear Entry. This truncates or clears the list at the presently displayed list point. Each list must be accessed and cleared separately.

On three-phase ac sources the voltage lists are phase selectable. You can output a different voltage list for each phase. To do this, use Phase Select to first choose the desired phase, as previously described in example 1 for setting the immediate output voltage.

5 - Trigger Delays and Phase Synchronization

The ac source trigger system also lets you program trigger delays as well as synchronize output changes to a specific phase angle of the output waveform.

In example ϕ, the output transient is triggered immediately at the receipt of the trigger signal. In example , a delay time of approximately 16.7 milliseconds elapses between the occurrence of the trigger and the start of the output transient. In example , the trigger source is programmed for phase synchronization, which means that the transient occurs at the first occurrence of the specified phase angle after the trigger signal is received. Example µ describes phase synchronization on three phase ac sources.

Note that phase synchronization is referenced to an internal phase signal. The output of the unit is normally offset by 0° with respect to this internal reference. Because synchronized transient events always occur with respect to the internal reference, the output will normally be in phase with the value programmed for phase synchronization. (The Phase command can be used to change the offset of the output with respect to the internal phase reference.)
