The edge trigger is the simplest type of trigger and uses a single trigger source to activate a
trigger. A trigger is activated when the trigger source exceeds (rises above) or drops (falls)
below the preset trigger level*.
In addition to input signals (CH1 to CH16 and 32-bits extended logic input), the external trigger
input signal and the commercial power supply signal can be used as a trigger source.
* “A trigger is activated” refers to the condition in which trigger conditions are satisfied and a waveform is
displayed.
Trigger level
A trigger is activated at this point if
"Rise" ( ) is selected.
