Generalized Trigger Model

An instrument trigger system synchronizes instrument actions with specified
events. An instrument action may be making a measurement or sourcing an
output signal. The events used to synchronize these actions include software
trigger commands, changing signal levels, and pulses on BNC connectors. The
trigger system also lets you specify the number of times to repeat certain
actions, and delays between actions. F'igure 1-13 is an example of a SCPI
trigger model.
