4.6 Instrument Subsystem
This subsystem programs the three-phase output capability of the AC Power Source.
Subsystem Syntax
INSTrument
:COUPle ALL | NONE Couple all phases for programming
:NSELect
Select the output phase to program (1|2|3)
:SELect Select the output phase to program (OUTP1|OUTP2|OUTP3)
INSTrument:COUPle
In a three-phase power source it is convenient to set parameters of all three output phases
simultaneously with one programming command. When INST:COUP ALL is programmed,
sending a command to any phase will result in that command being sent to all three phases.
INSTrument:COUPle only affects the operation of subsequent commands. It does not by itself
immediately affect the AC source's output. The commands that are affected by
INSTrument:COUPle are those with the designation: Phase Selectable.
INSTrument:COUPle has no affect on queries. There is no way to query more than one phase
with a single command. Directing queries to individual phases is done with INSTrument:NSELect.
Command Syntax INSTrument:COUPle
Parameters ALL|NONE
*RST Value ALL
Examples INST:COUP ALL
Query Syntax INSTrument:COUPle?
Returned Parameters
Related Commands INST:NSEL
INSTrument:NSELect
INSTrument:SELect
These commands allow the selection of individual outputs in a three-phase model for subsequent
commands or queries. Their operation is dependent on the setting of INSTrument:COUPle. If
INST:COUP NONE is programmed, then the phase selectable commands are sent only to the
particular output phase set by INSTrument:NSELect. If INST:COUP ALL is programmed, then all
commands are sent to all three output phases.
Note: If the power source is in SINGLE phase mode or does not support 3 phase mode of
operation, an INST:NSEL 2 or INST:NSEL 3 command will result in a
–222,”Data out of range”
error.
INSTrument:NSELect selects the phase by its number, while INSTrument:SELect references it by
name. These commands also select which output phase returns data when a query is sent.
Command Syntax INSTrument:NSELect
