LFRej specifies
low-frequency rejection coupling, which attenuates signals below
50 kHz before passing the signals to the trigger circuitry.
NOISErej specifies noise-rejection coupling, which provides stable triggering
by increasing the trigger hysteresis. Increased hysteresis reduces the trigger
sensitivity to noise but may require greater trigger signal amplitude.
Examples
TRIGGER:A:EDGE:COUPLING DC sets the A edge trigger coupling to D C.
TRIGGER:A:EDGE:COUPLING? might return :TRI GGER:A:EDGE:COUP LING
DC
indicating that the A edge trigger coupling is set to DC.
TRIGger:A:EDGE:SLOpe
Sets or returns the slope for the A edge trigger.

Syntax
TRIGger:A:EDGE:SLOpe {RISe|FALL}
TRIGger:A:EDGE:SLOpe?
Related Commands
TRIGger:A:EDGE:SOUrce, TRIGger:A:EDGE:COUPling
Arguments
RISe specifies to trigger on the rising or positive edge of a signal.
FALL specifies to trigger on the falling or negative edge of a signal.
Examples
TRIGGER:A:EDGE:SLOPE RISE sets the A edge trigger slope to positive, which
triggers on the rising edge of the signal.
TRIGGER:A:EDGE:SLOPE? might return :TRIGGER:A:EDGE: SLOPE FALL
indicating that the A edge trigger slope is negative.
TRIGger:A:EDGE:SOUrce
Sets or returns the source for the A edge trigger.
