Abstract

An integrated trigger function display system and methodology for trigger definition development in a signal measurement system having a graphical user interface. The system contemporaneously displays one or more trigger function names and an associated trigger function descriptor describing a trigger function identified by the associated trigger function name. The trigger name is displayed in a trigger name display region of a display window that concurrently displays a plurality of trigger function names. The descriptor is displayed in a trigger descriptor region of the display window so as to be visually-associated by the operator. A trigger definition is comprised of one or more trigger functions. Each trigger function is a graphical representation of an one or more underlying trigger primitives. A trigger primitive is a computer program statement that is translated into a form suitable for controlling the signal measurement system. Trigger primitives comprise one or more trigger branches used to form a sequence level of the trigger definition. For a selected trigger function, either the trigger function or its underlying trigger primitives are displayed in a trigger definition region of the display window for editing by the operator. Preferably, multiple such trigger functions or primitives may be selected and displayed simultaneously or sequentially to form a desired trigger definition.
