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 "Infinite
Persistence with Segmented Memory" on page 191) to show infinite persistence
across all acquired segments. See also "To set or clear persistence" on page 127
for details.
To acquire to
segmented
memory
1 Set up a trigger condition. (See Chapter 10 , “Triggers,” starting on page 137
for details.)
2 Press the [Acquire] key in the Waveform section of the front panel.
3 Press the Segmented softkey.
4 In the Segmented Memory Menu, press the Segmented softkey to enable
segmented memory acquisitions.
5 Press the # of Segs softkey and turn the Entry knob to select the number of
segments into which you would like to divide the oscilloscope's memory.
Memory can be divided into as few as two segments and as many as 250
segments.
6 Press the [Run] or [Single] key.
