Trigger
You can create your own start condition (trigger) for the trace. With the factory setting
(default setting) the trace starts as soon as you press the
button , you can define another trigger to start the measurement.
Using pretrigger, set the time for the recording before the trigger is set. As a consequence,
the trigger condition traces itself.
Example of a bit pattern as trigger:
You must define the pattern and value of a bit parameter for the trigger. To do so, proceed
as follows:
Using , select "Trigger to variable - bit pattern"

In the example, the trace starts if DI0 and DI3 are high and DI2 is low. The state of the other
digital inputs is not relevant for the start of the trace.
Further, you can either set an alarm or fault as start condition.
