Triggering
Trigger Types
There are five trigger types: Edge, Video, Pulse, Slope, and Alternative.
Access the trigger modes by pressing the TRIG MENU front panel button
(in the Trigger control group) and selecting Type from the Trigger menu.
Edge Triggering
1. Press the Type menu option button and select Edge.
2. Press the Source option button to choose a channel input (CHS 1 -
2; or CHS 1 - 4 on 4 channel models) or EXT, EXT/5, AC Line input.
3. Use Slope to select a positive or negative edge for Edge Triggering
(rising edge, falling edge, or both).
4. 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.
5. Press the Setup... option button to display the Trigger Setup...
menu. You can use the Trigger Setup... menu to select a coupling
mode and define a Holdoff value. Coupling modes comprise DC,
AC, HF Reject, and LF Reject. Turn the Adjust front panel knob to
set the Holdoff value.
