Trigger Types
The oscilloscope provides three trigger types: Edge, Video and Pulse.
Edge:
Edge trigger can be used in analog and digital circuits. An edge trigger
occurs when the trigger input passes through a specified voltage level in
the specified slope direction.
Video:
Use video trigger on fields or lines for standard video signals.
Pulse:
Use this trigger type to catch pulses with certain pulse width.
Settings for Edge Trigger
The Slope and Level controls help to define the trigger. The Slope control
determines whether the oscilloscope finds the trigger point on the rising or the
falling edge of a signal. To access the trigger slope control, press the MENU button,
select Edge, and use the Slope button to select Rising or Falling.
