Front Panel Operation - 4

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.

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.

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 occurence 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.
