INSTrument Subsystem
Instrument commands program the Primary/Secondary function of the instrument.
Primary/secondaryoperation is used when connecting a number of instruments in parallel to create a
system with higher total current and, hence, higher power.
In this document the terms “master” and “slave” have been replaced with “primary”
and “secondary.” The previous firmware version INSTrument Subsystem command
syntax is still supported in this and later firmware versions.
INSTrument:GROup:FUNCtion PRIMary|SECondary|NONe
INSTrument:GROup:FUNCtion?
Set the function of an instrument in a primary/secondary configuration. This setting is saved in non-
volatile memory.
PRIMary - Configures the instrument as the primary unit in a primary/secondary group.
SECondary - Configures the instrument as a secondary unit in a primary/secondary group.
NONE - disables the primary/secondary function. The unit operates independently.

PRIM|SEC|NONE
Configures the instrument as the primary INST:GRO:FUNC:PRIM
INSTrument:GROup:PRIMary:CONNect[:STATe] [,0|OFF|1|ON]
Instructs the primary unit to connect to the previously discovered secondary units. If the secondary
configuration on the bus matches the discovered one, the primary will start normal operation.
Otherwise the command will fail with an error, and all units will operate independently.
Parameter
Typical Return

value
>|MIN|MAX
INSTrument:GROup:PRIMary:CONNect:DELay? [MIN|MAX]
Set the delay after power-on before the primary unit attempts to connect to secondary units. This only
applies if the connect mode is set to AUTO. This setting is saved in-volatile memory.
Parameter
Typical Return
0 to 120 seconds
