The Analyzer Listing Menu
Markers
Off The Off selection turns all Stop measurement operations off. If the
stop measurement operation is not turned off and the stop measurement
criteria is met, the measurement will stop even though the markers are
set to other types or turned off.
X-O The X-O option is available in the Timing analyzer and in the State
analyzer with its count set to Time.
When X-O is selected, a repetitive run is stopped when a comparison of the
time period between the X and O markers and one of the time period options
is true.
Compare When you select Compare, a repetitive run is stopped when a
comparison of data in the Listing menu and data and criteria in the
Reference listing of the Compare menu matches an equality selection.
The equality selection is set from the Equal/Not Equal selection pop-up
menu.
Statistics markers
After patterns are assigned to the X and O markers, statistical information is
available when markers are set to Statistics.
In a State analyzer, Statistics markers only become available when the
Trigger menu Count field is set to Time.
Statistics are based on the time between the X and O. Both markers must be
found before valid statistical information is displayed.
