The manual start without triggering is the direct way to create a trace and to test
all telegrams. It is started with "Start Trace" (fig. 12 a). For this purpose the trigger
conditions described in the next sections must be switched off. This occurs with
the start of the software automatically. But it must be done manually if a trigger
condition was entered before. So set the "Number of Trigger Conditions" in all
three trigger levels to "0" additionally (details see below).
In fig. 12 in this case the field's b and c are skipped.

Trace with Trigger
The analyser offers additionally a sophisticated system of trigger
possibilities
for
the final start of traces which can be also combined:
5.7.4.1
Internal Trigger
During internal triggering from the observed telegrams in the analyser a signal is
derived which specifies the beginning of storage. The internal trigger runs over up
to three levels which are processed in sequence. A trace is taken up only if the
conditions of the trigger level1, then those of the trigger level 2 and finally those of
trigger level 3 are fulfilled.
Fig 13:
The trace trigger processes three levels in sequence. the trigger mask represented
here is the same for each of the three levels. Between the red marked fields an AND-
conjunction exists, the green marked fields are OR-linked. For details see text.
For adjustment of the possible options the
mask "Trace Trigger"
must be called
in the menu over options "
Trace Trigger
" or over the starting mask (fig 13). It con-
tains 3 levels which correspond to 3 trigger conditions which can be processed one
after another. The trigger event of the last level releases the race.
The following rules apply to the definition of the
trigger condition
to each level:
1.
Within
each red marked range from fig. 13 at least in each case one presetting
must be fulfilled in order to activate the trigger (that corresponds to a logical OR-
conjunction within these ranges).
