Timing analyzer markers
Timing analyzers always have marker choices of Pattern, Time, or
Statistics. Timing analyzers do not have state markers. The pattern
markers, though, can be used to count intervening patterns.
Stop measurement field
The stop measurement function specifies a condition that stops the
analyzer measurement during a repetitive run. If two analyzers are
configured, both analyzers stop when either specified stop condition is
satisfied.
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.
