List Transient

Lists are the most flexible means of generating multiple or synchronized transient outputs. The following figure shows a voltage output generated from a list. The output shown represents three different ac voltage pulses (160 volts for 33 milliseconds, 120 volts for 83 milliseconds, and 80 volts for 150 milliseconds) separated by 67-millisecond, 0-volt intervals.

The list specifies the pulses as three voltage points (point 0, 2, and 4), each with its corresponding dwell point. The intervals are three zero-voltage points (point 1, 3, and 5) of equal intervals. The count parameter causes the list to execute twice when started by a single trigger.

NOTE: From the Output Menu, execute the *RST command to reset the ac source. This is necessary because any previously programmed functions remain in effect until cleared.

Action

1.Press Voltage to access the Voltage Menu. Then press  to access the voltage mode command.

2.On the Entry keypad, press ↓ or ° to scroll through the mode parameters to obtain LIST and press Enter.

3.Access the List Menu by pressing Shift List. The first menu command is the count. From the Entry keypad, change the list count from the default (1) to 2. Press Enter.

4.Access the List menu again and press  until you access the dwell time. This specifies the "on" time for each voltage point, which is effectively the output pulse width. The first dwell point (0) appears in the display. On the Entry keypad, press . 0 3 3 and Enter.

5.Pressing the Enter key automatically advances to the step in the list. Enter the following values for dwell list points 1 through 5: .067, .083, .067, .150, .067. 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.
