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.
