Sampling modes are accessed by
pressing the SETUP button in the
HORIZONTAL control group.
There are three basic sampling modes:
Normal -- real-time mode
Peak Detect -- the maximum and

Average -- up to 256 waveforms

available:
Equivalent Sampling Mode -- random
interleaved sampling (RIS) mode
Roll mode -- for slow acquisitions
You can change the timebase at any time without
displaying the “Horizontal” setup menu.
As you turn the time/div knob in the HORIZONTAL
control group, the value is displayed at the top-left of the
screen:
