TRIGger:B Subsystem
TVS600 & TVS600A Command Reference
2–257
TRIGger:B:SOURce
TRIGger:B:SOURce?
Sets or queries the source of the trigger signal for the trigger B circuit. You can
specify only one source at a time.
Setting source to INTernal1 selects the signal from INPut1 and [SENSe:]VOLT-
age1 as the trigger source. The EXTernal signal is from the front-panel BNC
connector labeled External Trigger Input. Setting the source to IMMediate will
bypass event detection in the trigger B circuit forcing a trigger B event.
Many commands in the TRIGger subsystem are dependent on the trigger source
you select. For instance, the TRIGger:B:COUPling setting is ignored when you
set the trigger source to EXTernal. The dependencies for each command are
listed with the command description.

instrument has two channels.
Changing the trigger B source from INTernal to EXTernal or from one INTernal
source to another INTernal source with a different VOLTage:RANGe setting may
change the TRIGger:B:LEVel setting to accommodate a new vertical range.
