12 Acquisition Control
When using segmented memory, use the Analyze Segments feature (see
"Measurements, Statistics, and Infinite Persistence with Segmented Memory" on
page 197) to show infinite persistence across all acquired segments. See also "To
set or clear persistence" on page 131 for details.
To acquire to
segmented
memory
1 Set up a trigger condition. (See Chapter 10, “Triggers,” starting on page 141
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 #ofSegs 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 500
segments with the standard 2M points of memory or 1000 segments with the
upgrade to 4M points memory.
6 Press the [Run] or [Single] key.
The oscilloscope runs and fills 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 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" on page 176.
