Pulse Transient
In the following example, the output is four 83.3-millisecond, 120 Vrms pulses at 60 Hz. The figure
shows the trigger, pulse count, pulse period, and duty cycle.
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.

1. Press Voltage to access the Voltage Menu. On the Entry keypad, press 1 0 2 Enter . VOLT 102
2. Press
ô to access the triggered voltage command. On the Entry keypad, press 1 2 0
Enter .
VOLT 120
3. Access the Voltage Menu again and press
ô to access the voltage mode command. On
the Entry keypad, press
¯ or ° to scroll through the mode parameters to obtain
PULSE and press Enter .

4. Press Pulse to access the Pulse Menu. From the Entry keypad, press
. 0 8 3 3 Enter to enter a pulse width of 83.3 milliseconds.

5. Access the Pulse Menu and press
ô to access the duty cycle command. From the Entry
keypad, press 3 3 Enter to change the duty cycle to 33%.

6. Access the Pulse Menu and press
ô to access the pulse count. On the Entry keypad,
press 4 and Enter .
COUNT 4
7. Press Trigger Control and Enter to initiate the transient trigger sequence. INIT:IMMED
8. Press Shift Trigger . This sends the ac source an immediate trigger signal to generate
the four output pulses.
Note: The ac source output returns to 102 V at the completion of the output pulses.
102 V 60 HZ
On three-phase ac sources the voltage pulses are phase selectable. You can output a different voltage
pulse 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.
