Commands listed in alphabetical order
Arguments
B<x>
sets the selected 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 trigger 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 menu, 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 attenuates signals below 80 kHz before passing the signals to the
trigger circuitry.
NOISErej
coupling provides stable 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:COUPLING
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
