waveform file. That is, the same sequencing list file can be reused for different
multi-segment waveform files with the same number of segments.
Changes and recalculations of a multi-segment waveform file cause a recheck
whether the assigned sequencing list files are still valid. A message is displayed to
inform about necessary corrections in the “play list”.
5.10.2.4 Impact of the Marker Settings
The general purpose of the marker signal is the triggering of the DUT (device under
test) and the synchronization with other measurement instruments.
For better flexibility, the instrument provides several possibilities to define marker sig-
nals:
●
Segment markers
Because the multiple segments are standalone waveforms, they can already carry
marker signals. You can define how the instrument processes these available
marker signals. The instrument can ignore them or use them in the composed
multi-segment waveform.
●
Additional segment restart and sequence restart markers
Additional marker signal can be defined to restart the multi-segment sequence or
to restart each of the multiple segments. A marker output configured and defined
for one of these purposes overwrites markers that use the same output connector
and that are defined in the individual waveforms.
Figure 5-28: Example of marker signals
The segment begin is defined by the low-high slope of the marker, which applies
for switching between two segments and if there is a segment replay.
●
General marker signals for the composed multi-segment waveform
The "ARB" dialog provides also access to the standard marker settings. Settings
other than "unchanged" overwrite existing marker in the waveforms or markers
defined for the multi-segment waveform.
The Figure 5-29 shows schematically how the instrument evaluates the priorities of the
different marker signals, if multiple marker signals are mapped to the same connector.
