12 Acquisition Control
When using segmented memory, use the Analyze Segments feature (see
"Measurements, Statistics, and Infinite Persistence with Segmented Memory" on
page 173) to show infinite persistence across all acquired segments. See also "To
set or clear persistence"
on page 124 for details.
To acquire to
segmented
memory
1 Set up a trigger condition. (See Chapter 10, “Triggers,” starting on page 135
for details.)
2 Open the Acquire dialog box by selecting the sample rate and memory depth
(Acquire) badge or by choosing Setup > Acquire... from the main menu.
3 In the Acquire dialog box, select Segmented....
4 In the Segmented dialog box, select the # of Segments field 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 1000
segments, depending on the oscilloscope model.
5 Select the Segmented check box to enable segmented memory acquisitions.
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 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 Trig'd trigger mode to prevent Auto triggering. See
"To select the
Auto or Trig'd trigger mode"
on page 154.
