Notice that there are two trigger configuration structures: BASIC and ADVANCED. The basic menu
structure can be used when simple trigger operations suffice. The advanced menu structure must be
used when more sophisticated trigger operations (such as scanning) are required. The differences
between basic and advanced triggering are explained below.
