Acquisition Control
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 and digital channel (on
MSO models) data.
When using segmented memory, use the Analyze Segments feature (see
"Infinite Persistence with Segmented Memory" on page 157) to show
infinite persistence across all acquired segments. See also "To set or clear
persistence" on page 103 for details.
To acquire to
segmented
memory
1
Set up a trigger condition. (See Chapter 9 , “Triggers,” starting on page
113 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 25
segments.
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 136.
