The pretrigger part of the waveform can help troubleshooting, for example, to find the
cause of a glitch. The posttrigger part shows what follows the trigger.
Trigger offset
Adds a time offset to the reference point to choose the part of the waveform to be captured
and shown in the diagram. Thus, you can set the trigger outside the diagram and analyze
the signal some time before or after the trigger. Positive values move the trigger to the
right of the reference point to show the pre-trigger part of the signal.
SCPI command:
TIMebase:POSition on page 429
Reference point
Sets the zero point of the time scale in % of the display between 10% and 90%. The
reference point defines which part of the waveform is shown. If the "Trigger offset" is zero,
the trigger point matches the reference point.
SCPI command:
TIMebase:REFerence on page 430
Restrict offset to acquisition range
Ensures that the trigger occurs within one acquisition cycle. If enabled, the trigger cannot
be set outside the waveform diagram.
SCPI command:
TRIGger<m>:OFFSet:LIMited on page 489
Show trigger lines permanently
Displays the trigger levels and the hysteresis in the diagrams until you disable this option.
SCPI command:
