Tektronix TVS600 & TVS600A Series Manuel D’Utilisation

TRIGger:B Subsystem

TVS600 & TVS600A Command Reference

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.

Execution Error –141, “Invalid character data”
Attempted to set the trigger source to an illegal value.

Execution Error –221, “Settings conflict.”
Attempted to set trigger source to a value other than IMMediate when TRIG-
ger:TYPE is set to PULSe.

Execution Error –241, “Hardware missing”
Attempted to set the trigger source to INTernal3 or INTernal4 when the
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.
