Trigger system
Trigger system
The trigger system is responsible for such tasks as detecting the start of a measurement
cycle (triggering) and enabling/disabling measurement on each channel. As shown in
Figure 5-1, the trigger system has two types of state: system-wide and channel-wide. The
system-wide state can be “Hold”, “Waiting for Trigger”, or “Measurement” while the
channel-wide state can be “Idle” or “Initiate”.
Figure 5-1 Trigger system
The following subsections describe each state and how the trigger system switches among
the states.
