142 Keysight InfiniiVision 1200 X-Series and EDUX1052A/G Oscilloscopes User's Guide
13 Acquisition Control
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 auto-triggering. See "To select the
Auto or Normal trigger mode" on page 122.

Navigating Segments
1 Press the Current Seg softkey and turn the Entry knob to display the desired
segment along with a time tag indicating the time from the first trigger event.
Infinite Persistence with Segmented Memory
When data has been acquired to segmented memory, you can also turn on infinite
persistence (in the Display menu) and press the Analyze Segments softkey to create
an infinite persistence display. The Analyze Segments softkey appears when the
acquisition is stopped and the segmented memory feature is on.
Segmented Memory Re-Arm Time
After each segment fills, the oscilloscope re-arms and is ready to trigger in about
1µs.
Remember though, for example: if the horizontal time per division control is set to
5 µs/div, and the Time Reference is set to Center, it will take at least 50 µs to fill all
ten divisions and re-arm. (That is 25 µs to capture pre-trigger data and 25 µs to
capture post-trigger data.)
