2.2 Triggering
A trigger is a cue used to display the waveform on the screen. A trigger occurs when the specified
trigger condition is met, and a waveform is displayed on the screen.
Trigger Modes
The trigger mode determines the conditions for updating the displayed waveforms. There are six
trigger modes: Auto, Auto Level, Normal, Single, N Single, and On Start. The trigger mode setting
applies to all trigger types.
Trigger Types
Triggers can be broadly divided into “simple triggers” and “enhanced triggers.”
Simple Triggers
Input Signal Trigger
The DL850/DL850V triggers when the trigger source passes through the specified trigger level in
the specified way (rising edge, falling edge, or rising or falling edge).
Time Trigger
The DL850/DL850V triggers at the specified date and time and at specified intervals afterwards.
External Signal Trigger
The DL850/DL850V triggers when the signal applied to the TRIG IN terminal passes through the
specified trigger level in the specified way (rising or falling edge).
Power Line Signal Trigger
The DL850/DL850V triggers on the rising edge of the power supply signal that it is receiving. This
trigger enables you to observe waveforms in synchronization with the power supply frequency.
Enhanced Triggers
A -> B(N) Trigger
After state condition A is met, the DL850/DL850V triggers when state condition B is met N times.
