Trigger Settings
The oscilloscope provides three trigger modes: edge, pulse, and TV. Pulse width
trigger is used to find pulses with certain pulse widths. TV is used to trigger on
fields or lines for standard video waveforms.
Edge Trigger
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.
