If Binary format is selected, the state of the data lines may be
specified as a binary number including 'don't cares'. If a line is specified
as a don't care, it is not used by the trigger comparison circuitry.
The state of any bus management line may be specified as asserted
(1), unasserted (0), or 'don't care' (X).
The Match Count specifies the number of times the selected match
pattern must be presented on the bus before the Delay Count (if it is not
zero) will be decremented. The match count may be a number between 1
and 65,535. If the Delay Count is zero, the Match Count specifies the
number of times the selected match pattern must be presented on the bus
before the Post Trigger Count (if it is not zero) will be decremented.
The Delay Count specifies the number of events that must occur
before the Post Trigger Count is decremented. (1 to 9,999,999)
The Post Trigger Count specifies the number of events that must
occur after the trigger point has been found (1 to 32,767). When the Post
Trigger Count has be decremented to Zero, the Record Complete Action
will occur.
When the Analyzer488 has finished recording the specified amount
of bus events, one of two things will occur depending on the Record
Complete selection.
If Stop is selected, the Analyzer488 will stop recording data and
allow further bus events to occur. The Handshake selection is not
changed.
If Step is selected, the Analyzer488 will automatically go into Step
Handshake speed, recording will remain on, and one additional bus event
will be recorded each time the Step command is issued.
The Trigger Description box will describe the current trigger setup
in text format.
Pressing the OK button enters the current trigger setup and closes
the trigger setup window.
