7. Press the Mode option button to select Auto, Normal, or Single
mode. Use Auto mode to let the acquisition automatically run in
the absence of a trigger. Use Normal mode when you want to see
only valid triggered waveforms (when you use this mode the
oscilloscope does not display a waveform until after the first
trigger). Use Single mode when you want the oscilloscope to
acquire a single waveform.
8. Press the Setup... option button to display the Trigger Setup...
menu. You can use the Trigger Setup... menu to select a coupling

AC, HF Reject, and LF Reject. Turn the Adjust front panel knob to
set the Holdoff value.
Alternative Triggering
The trigger signal comes from two vertical channels when you use
Alternative Triggering. Using this type of trigger, you can observe two
unrelated signals at the same time. For each signal, you can select
different trigger types, such as Edge, Pulse, Slope, or Video. Trigger
information for the two channels is displayed at the bottom right side of
the display.
1. Press the Type option button and select Alternative.
2. Set up both triggers by pressing the Source option button and
selecting a Source - CH1 or CH2 (or CH3 or 4 on 4 channel models).
3. For the selected Source, press the Mode option button and select
a Trigger Type (Edge, Pulse, Slope, or Video).
