Acquiring to Segmented Memory

When capturing multiple infrequent trigger events it is advantageous to
divide the oscilloscope's memory into segments. This lets you capture
signal activity without capturing long periods of signal inactivity.
Each segment is complete with all analog channel, digital channel (on MSO
models), and serial decode data.
When using segmented memory, use the Analyze Segments feature (see
"Measurements, Statistics, and Infinite Persistence with Segmented
Memory"

The oscilloscope runs and fills a memory segment for each trigger event.
When the oscilloscope is busy acquiring multiple segments, the progress is
displayed on screen. The oscilloscope continues to trigger until memory is
filled, then the oscilloscope stops.
If the signal you are measuring has more than about 1 s of inactivity,
consider selecting the Normal trigger mode to prevent AutoTriggering. See
"To select the Auto or Normal trigger mode"

Memory can be divided into as few as two segments and as many as
1000 segments, depending on the oscilloscope model.
