Using Roll Mode
Roll mode gives a display similar to a strip chart recorder for low-frequency
signals. Roll mode lets you see acquired data points without waiting for the
acquisition of a complete waveform record.
Roll mode is enabled when the trigger mode is auto and the horizontal scale is set
to 40 ms/div or slower.
Quick Tips
■ Switching to Envelope or Average acquisition mode, using digital channels,
using math waveforms, turning on a bus, or switching to Normal trigger will
disable Roll mode.
■ Roll mode is disabled when you set the horizontal scale to 20 ms per division
or faster.
■ Push Run/Stop to halt Roll mode.
Act on Event
Have the oscilloscope perform a defined action after a defined event has
occurred. The event can be a trigger or a certain number of acquisitions. The
action can be to:
■ Stop acquisitions
■ Save a waveform or a screen image to a file
■ Print
■ Send a pulse out the AUX OUT port
■ Generate a remote interface SRQ
■ Send an e-mail notification
■ Display a message on the oscilloscope display
