460 Trend 1 Continuous Trigger
[Tr1 Cont Trigger]
Tr1 Cont Trigger specifies the type of trend. You can
choose either 0 for one–shot or 1 for continuous.
With a one–shot trend, once the trigger condition is
true and the number of samples after the trigger is
taken are gathered, the trend stops.
With a continuous trend, once the trigger condition is
true and the number of samples after the trigger is
taken are gathered, the trend continues looking for
the next occurrence of a true trigger condition.
