Figure l-35. Generalized Trigger ModelDetails of Trigger States

These paragraphs use flow charts to explain the decision making rules inside each trigger state. These rules govern how the instrument moves between adjacent states. Some of the flow charts reference commands that have not been discussed yet. These commands

are explained later in this subsection. Keep in mind that this explanation covers the most general case. Your particular instrument may not implement all of the commands discussed here.

Inside the Idle State. Figure l-36 illustrates the operation of the idle state.
