INSTrument:SELect

This command may be used select a specific output phase in three-phase mode using a

character reference. “A” denotes phase A, “B” denotes phase B and “C” denotes Phase C.

As long as the instrument state is coupled however, programming command will affect all

phases. As soon as the INST:COUP NONE command is issued, the last selected phase

becomes selected. To immediately change the output of a single phase only, make sure the

instrument state is uncoupled when issuing the INST:SEL command.

Note that the MEASuse and FETCh subsystems are not affected by the INST:COUP

command and always operate on the selected phase only. This means the instrument can

remain in coupled mode while doing measurement queries using “INST:SEL

<n>;FETC:VOLT?;*WAI”. Note that when the instrument is subsequently put in the

uncoupled state using “INST:COUP NONE”, the last issued phase selection will be in effect.

To make sure the desired phase is selected, follow the “INST:COUP NONE” command with

an “INST:SEL <n>” command
