Trigger Modes
The oscilloscope provides three trigger modes: edge, pulse, and video. Edge
trigger can be used with analog and digital circuits. An edge trigger occurs when
the trigger input passes through a specified voltage level with the specified
slope. Pulse trigger is used to find pulses with certain pulse widths. Video is
used to trigger on fields or lines for standard video waveforms.
Edge Trigger
The Slope and Level controls help to define the Edge trigger. The Slope control
determines whether the oscilloscope finds the trigger point on the rising or the
falling edge of a waveform. The Level control determines voltage point on the
waveform where the trigger occurs.
