Logical expression
Defines a logic combination of several digital channels as trigger condition if "Logic" is
set for "Source". The "Qualification Editor" supports the entry of the expression.

11.3.4.7 Pattern
The pattern trigger identifies a logical state of several logically combined digital channels
(pattern) and a time limitation (holdoff). The pattern definition is defined by the logical
expression, if "Logic" is used for trigger source. For a parallel bus trigger source, the
pattern is defined by setting the state of each digital channel.
The timing starts when the pattern comes true. The decision level is the logical threshold.

Channel states
For each digital channel that is used in the bus, set the required state: 1, 0, or X (don't
care).
