Triggering
Trigger Types
There are five trigger types: Edge, Video, Pulse, Slope, and Alternative.
You can access 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 or external 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.
