Measurements, Statistics, and Infinite Persistence with Segmented
Memory
To perform measurements and view statistical information, press [Meas] and set up
your desired measurements (see Chapter 15, “Measurements,” starting on page
243). Then, press Analyze Segments. Statistical data will be accumulated for the
measurements you have chosen.
The Analyze Segments softkey appears when the acquisition is stopped and the
segmented memory feature is on or when the serial Lister is enabled.
You can also turn on infinite persistence (in the Display Menu) and press the
Analyze Segments softkey to create an infinite persistence display.
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.)
Saving Data from Segmented Memory
You can save either the currently displayed segment (Save Segment - Current), or all
segments (Save Segment - All) in the following data formats: CSV, ASCII XY, and
BIN.
Be sure to set the Length control to capture enough points to accurately represent
the captured data. When the oscilloscope is busy saving multiple segments,
progress is displayed in the upper right area of the display.
For more information, see “To save CSV, ASCII XY, or BIN data files" on page 324.
