Edge Terms If you want to qualify an edge, place the appropriate edge
on the data channel you are watching. When the analyzer sees the
correct edge, the term becomes true.
Edge terms can be used singularly or in combination with each other across
all assigned channels. When you specify an edge on more than one channel,
the analyzer ORs the edges.

The following edge choices are available for each bit:
•
Positive edge (↑)
•
Negative edge (↓)
•
Either positive or negative (↕)
•
No edge (.)
After the assignment menu closes, you may see "$" indicators in the
assignment field display. This symbol indicates the assignment can't totally
be displayed in the selected base. It was assigned in another base. When
Binary is selected for the numeric base, you see the actual assignments.
Range Terms Range terms bracket groups of bit patterns. Each Range
term is assigned to either of the two analyzers, but not both. You assign
an upper and lower bit pattern boundary. The range is recognized as the
data that is numerically between or on the two specified boundaries. In
addition, the range must be contained in a single pod pair, with no clock
bits allowed.
To assign bit patterns to the upper and lower boundaries of a Range term,
you use a pop-up keypad. The keypad appears when you select the upper or
lower Range term assignment fields.
