Logic pattern and state pattern editor (bus tab)
Use the controls to set up the Logic Pattern or the Logic State trigger pattern for the instrument to use
to detect a bus value.
The maximum pattern size (number of bits) for Logic Pattern or Logic State trigger is 20 b its. The display
pattern format is binary, hexadecimal, ASCII, or decimal. The pattern display format can also be symbolic.
The binary p
attern uses the symbols 0, 1, and X (it is a do not care bit and is not case-sensitive). The
hexadecimalpatternusesthesymbols0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,andX.Fivehexadecimal
characters will convey all 20 digital inputs. The characters show up in the binary, hexadecimal, ASCII, and
decimal fields. The non-selected e ntries are a utomatically populated with the correct data corresponding
to what you enter in the selected entry field. An X is shown in the field when you do not enter enough
characters.
