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  to access the triggered voltage command. On the Entry keypad, press 1 2 0	VOLT	120
	Enter.
3.	Access the Voltage Menu again and press  to access the voltage mode command. On	VOLT:M	PULSE
	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	WIDTH	.0833
	. 0 8 3 3 Enter to enter a pulse width of 83.3 milliseconds.
5.	Access the Pulse Menu and press  to access the duty cycle command. From the Entry	DCYCLE	33
	keypad, press 3 3 Enter to change the duty cycle to 33%.
6.	Access the Pulse Menu and press  to access the pulse count. On the Entry keypad,	COUNT	4
	press 4 and Enter.
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	102 V 60 HZ
	the four output pulses.

Note: The ac source output returns to 102 V at the completion of the output pulses.

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.
