Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger
circuit. Please distinguish it withChannel Coupling.
DC: allow DC and AC components into the trigger path.
AC: block all the DC components and attenuate signals lower than 8 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 that trigger
coupling is only valid in edge trigger.
