For example, the entire measurement can be recorded in Toggle Trigger mode by
selecting Start and Stop as the trigger conditions. In this case, a start-of-block trigger
is activated at the start of measurement, and the measurement is logged until the
end-of-block trigger occurs when the measurement is stopped. Pre-trigger and posttrigger
times are ignored when this option is set.
You can determine whether the trigger action should be executed once or multiple
times. If the option Measurement stop after n triggers is selected in the trigger's
configuration dialog, the measurement process is stopped after the post-trigger time
of the nth trigger has elapsed.
2.7.1.2 Trigger Events
You can define trigger events using the five check boxes in the configuration dialog.
The following types are available to you:
The following types are available:
• Trigger on Start. Triggering occurs unconditionally and immediately at the start
of measurement. The logging time period is defined exclusively by the posttrigger
time in this case.
• Trigger on Stop. Triggering is executed at the end of the measurement. Triggering
can be activated by the CAPL function stop() or by the key. The
logging time period is defined exclusively by the pre-trigger time in this case.
• Trigger by a CAPL program: Using CAPL programming methods arbitrarily
complex conditions can be formulated, which can depend on the occurrence of
various events. Triggering is activated when the intrinsic function trigger() is
called by a procedure. The configured pretrigger and post-trigger times define
the logging time period for this trigger.
• Trigger when certain messages occur. With the Event trigger type, triggering
occurs when specific messages with specific attributes occur. To define these
attributes press the [Condition] button. The configured pretrigger and posttrigger
times define the logging time period for this trigger.
• Trigger on Error frames. Triggering is executed whenever an error frame occurs.
The configured pretrigger and post-trigger times define the logging time
period for this trigger.
2.7.1.3 Time window
In the configuration dialog you also define the time window (the pre-trigger and posttrigger
times in milliseconds) around each trigger.
The pre-trigger time defines the time interval before activation of the trigger condition
which is to be saved. If the trigger condition occurs so early that the pre-trigger time
is greater than the time since the start of the measurement, only those data occurring
prior to the trigger can be saved. Valid pre-trigger times must lie in the range of 0 to
180000 ms.
