:TRIGger:OUTPut#:SERial?

Syntax:

:TRIGger:OUTPut#:SERial?

Returns the serial number of the module that holds this trigger output. Note that a trigger module

has two trigger outputs, so there are always two trigger outputs that report the same serial number.

Example query:

TRIG:OUTP0:SER?

Example response:

"DE000001"

:TRIGger:OUTPut#:TYPE?

Syntax:

:TRIGger:OUTPut#:TYPE?

Returns the product type of the module which holds this trigger output.

Example query:

TRIG:OUTP0:TYPE?

Example response:

"BIT-3004B"
