Segmented Memory

You can purchase the oscilloscope with the segmented memory option
factory- installed (Option SGM) or you can easily install it yourself (order
model number N5454A "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 "dead time."
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"
infinite persistence across all acquired segments. See also
infinite persistence"

Using segmented memory

1 Set up a trigger condition. (See
2 Press the [Acquire] key in the Waveform section of the front panel.
3 Press the Segmented softkey to access the Segmented Memory Menu.
4 In the Segmented Memory Menu, press the Segmented softkey to enable
5 Press the # of Segs softkey and rotate the Entry knob to select the
6 Press the [Run] key or the [Single] key.
The oscilloscope will run and fill a memory segment for each trigger
event. When the oscilloscope is busy acquiring multiple segments, the
progress is displayed in the upper right area of the display. The
oscilloscope will continue to trigger until memory is filled, then the
oscilloscope will stop.

oscilloscope's memory. Memory can be divided into as few as two
segments and as many as 2000 segments.
