PXD Series Digitizer
Sequence – Working With Segments
In sequence mode, the complete waveform consists of a number of fixed-size segments acquired
in single-shot mode. Select the number of segments to be captured, then select each segment
individually. Each trigger fills a new segment.
Sequence offers a number of unique capabilities. With it, dead time is limited between trigger
events for consecutive segments. The Digitizer can capture in fine detail complicated sequences
of events over large time intervals, while ignoring the uninteresting periods between the events.
Time measurements can be made between events on selected segments using the full precision
of the acquisition timebase.
Trigger time stamps of 1 ns resolution are given for each of the segments in the Text & Times Sta-
tus menu. Each individual segment can be read out by the controller.
The Digitizer uses the sequence timebase setting to determine the capture duration of each seg-
ment: 10 x time/div. The digitizer uses this setting — with the desired number of segments, maxi-
mum segment length and total available memory — to determine the actual number of samples or
segments, and time or points.
