Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger
circuit. Note to distinguish it with "Channel Coupling".
DC: allow the DC and AC components to pass 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 5 kHz.
HF reject: reject the high frequency components higher than 50 kHz.
Press MENU (in the trigger control area (TRIGGER) on the front panel) Setting
Coupling to select the desired coupling type (the default is DC).
Note: Trigger coupling is only valid in edge trigger.
