Trigger system
The trigger system is responsible for tasks such as detecting the start of a measurement
cycle (triggering) and controlling the system state. As
shows, the trigger system
has a system-wide state that can be “Idle,” “Waiting for Trigger,” or “Measurement.”

Trigger system
The following subsections describe each state and explain how the trigger system switches
among the states.
System-wide states and transitions
Idle state
When the following commands are executed, the trigger system transitions to the idle state
(e in
). The idle state is also in effect immediately after power-on. Because the
continuous activation of the trigger system and the trigger mode are set to ON and internal
trigger, respectively, at power-on, the trigger system immediately transitions to the waiting
for trigger state and then repeats the transition between the measurement state and the
waiting for trigger state.
