In the following program, the SSRC EXT event is used with synchronous AC
voltage measurements. After the trigger event occurs (the trigger arm and sample
events are AUTO), the first low-going TTL transition on the Ext Trig connector
initiates the first burst. Each successive external trigger will then initiate a burst
until the necessary number of bursts are completed.
