Arguments
AC selects AC tr
igger coupling.
DC selects DC coupling.
HFRej coupling removes the high-frequency components of the DC signal.
LFRej coupling removes the low-frequency components of the AC signal.
NOISErej selects DC low sensitivity. It requires added signal amplitude for
more stable, less false triggering.
Examples
TRIGGER:MAIN:EDGE:COUPLIN G DC sets the main edge trigger coupling to DC.
TRIGger:MAIn:EDGE:SLOpe
Selects a rising or falling slope for the edge trigger. This is equivalent to setting
the Slope option in the Trigger menu.

Arguments
FALL specifies to trigger on the falling or negative edge of a signal.
RISe specifies to trigger on the rising or positive edge o f a signal.
Examples
TRIGGER:MAIN:EDGE:SLOPE RISE sets the main edge trigger to occur on the
rising slope.
