7 Acquisition Modes
236 InfiniiVision 7000B Series Oscilloscopes User’s Guide
does when Segmented Memory mode is not selected. The Knob softkey also
appears in the Horizontal Menu so you can make the same adjustments
there.
Measurements, statistics, and infinite persistence
To perform measurements and view statistical information, press [Meas]
and set up your desired measurements. (See “List of Automatic
Measurements” on page 154.) Then press Analyze Segments. Statistical data
will be accumulated for the measurements you have chosen.
The Analyze Segments softkey only appears when the acquisition is stopped
and the optional segmented memory feature is on.
You can also turn on infinite persistence (in the Display Menu) and press
the Analyze Segments softkey to create an infinite persistence display.
Re-arm time
After each segment fills, the oscilloscope re- arms and is ready to trigger
in about 8 s. Remember though, for example: if the horizontal time per
division control is set to 5 s/div, and the Time Reference is set to Center,
it will take at least 50 s to fill all ten divisions and re- arm. (That’s 25 s
to capture pre- trigger data and 25 s to capture post- trigger data.)
