Commands listed in alphabetical order
Arguments
B<x> sets the se
lected source to the bus.
Examples
TRIGGER:A:BUS:SOURCE B2 sets the selected source for the bus trigger to Bus 2.
TRIGGER:A:BUS:SOURCE? might return TRIGGER:A:BUS:SOURCE B1,
indicating that the selected source for the bus t rigger is set to Bus 1.
TRIGger:{A|B}:EDGE:COUPling
This command sets or queries the type of coupling for the edge trigger. This
command is equivalent to selecting Edge from the Trigger Type drop-down in the
Trigger setup context m enu, and choosing from the Coupling drop-down list.

TRIGger:{A|B}:EDGE:SOUrce, TRIGger:{A|B}:EDGE:SLOpe
Arguments
DC selects DC trigger coupling, which passes all input signals to the trigger
circuitry.
HFRej coupling attenuates signals above 50 kHz before passing the signals to the
trigger circuitry.
LFRej coupling a ttenuates signals below 80 kHz before passing the signals to the
trigger circuitry.
NOISErej coupling provides s table triggering by increasing the trigger hysteresis.
Increased hysteresis reduces the trigger sensitivity to noise but can require greater
trigger signal amplitude.
Examples
TRIGGER:A:EDGE:COUPLING DC sets the A edge trigger coupling to DC.
TRIGGER:A:EDGE:COUPLING? might return :TRIGGER:A:EDGE:COUP LING
DC
, indicating that the A edge trigger coupling is set to DC.
TRIGger:{A|B}:EDGE:SLOpe
This command sets or queries the slope for the edge trigger. This command is
equivalent to selecting Edge from the Trigger Type drop-down in the Trigger
