Starting Measurement Cycle (Triggering) and Detecting End of Measurement

Starting a New Measurement Cycle (Triggering)

Trigger system

The trigger system is responsible for such tasks as detecting the start of a measurement

cycle (triggering) and controlling the pre-measurement delay time. As shown in Figure 5-1,

the trigger system has three states: Idle, Waiting for Trigger, and Measurement.

Figure 5-1 Trigger system

The following subsections describe each state and how the trigger system switches among

the three states.

Idle state

The trigger system is put into Idle state (arrow e in Figure 5-1) when you power on the

instrument or issue one of the following commands:

• *RST on page 206

• :ABOR on page 209

The trigger system is put into Waiting for Trigger state (arrow a in Figure 5-1) when you

activate it with one of the following commands:

• :INIT on page 287

• :INIT:CONT on page 287 (“ON” specified)
