13.6.3 Parameterization
In the main menu you can select
– the axis/spindle to be measured
– the signal to be measured
– the measuring period
– the triggering time
– the type of triggering
– the triggering threshold.
The cursor must be positioned on the “Axis/spindle name” list box of the trace
concerned. You can select it with the soft keys Axis+ and Axis– or by accepting
a value from the drop-down list.
The cursor must be positioned on the “Signal selection” list box of the trace
concerned. You can select a value by accepting it from the drop-down list.
The measuring time is written directly into the “Measuring duration” input field.
Direct input of pretriggering and posttriggering.
With negative input values (sign minus –) recording starts in advance of the
triggering event by the time set.
With positive input values (without sign) recording starts
the time set after the triggering event.
Boundary condition: Trigger time + measurement duration
y
0.
The trigger type is chosen from the drop-down list Trigger.
The trigger always refers to trace 1. Once the triggering conditions are fulfilled
traces 2 to 4 are started simultaneously.
Settable triggering conditions:
S
No trigger, i.e. measurement starts when you operate the soft key Start (all
traces are started in synchronism).
S
Positive edge
S
Negative edge.
Direct input of the triggering threshold.
The threshold is only active with the types of triggering “Positive edge” and
“Negative edge”.
The unit refers to the signal selected.
