TRIGger[:A] Subsystem
TVS600 & TVS600A Command Reference
2–231
TRIGger:COUPling
TRIGger:COUPling?
Sets or queries whether the source of the A trigger is AC or DC coupled. AC
coupling removes any DC component from the signal. DC coupling passes all
frequencies equally. This command is effective only when you set TRIG-
ger:SOURce to an INTernal source. Note that the external trigger is limited to
DC coupling only.
You may want to review the command TRIGger:COUPling:<preset> which lets
you set trigger coupling and filtering with one command. However, that
command does not adhere to the SCPI standard.

Changing trigger coupling from DC to AC sets TRIGger:FILTer[:LPASs] to OFF
and may cause TRIGger:LEVel to change if the level is out of range for AC
coupling. Changing trigger coupling from AC to DC sets TRIGger:FIL-
Ter:HPASs to OFF.
When TRIGger:A and TRIGger:B share the same SOURce, changing COUPling
for one will change COUPling for the other.
