Trigger Coupling

Trigger coupling decides which kind of components will be transmitted to the trigger
module. Please distinguish it with “Channel Coupling”.
 DC: allow DC and AC components into the trigger path.
 AC: block all the DC components and attenuate signals lower than 75 Hz.
 LF Reject: block the DC components and reject the low frequency components

(lower than 75 kHz).

 HF Reject: reject the high frequency components (higher than 75 kHz).

Press MENU  Setting  Coupling in the trigger control area (TRIGGER) at the
front panel to select the desired coupling type (the default is DC).

Note:

Trigger coupling is only valid in edge trigger and the trigger source is not any

channel of D0-D15).
