Programmable AC Source 6460/6463/6490 User’s Manual
In a multi-phase power source it is convenient to set parameters of all phases simultaneously
with one programmed command. When INST : COUP ALL command is programmed, a
command will be sent to the AC source, and to all phases in the end. INST : COUP NONE
command cancels COUP ALL command. This command only affects set voltage.
This command has no effect on queries and can set parameters only.
INSTrument : NSELect 1| 2| 3
INSTrument : SELect OUTPut1| OUTPut2| OUTPut3
Query syntax INSTrument : NSELect?
Return parameters 1| 2| 3
This command sets individual outputs in a multi-phase model for subsequent commands or
queries. If INST : COUP NONE is programmed, the phase-selective commands are sent to
the particular output phase set by INSTrument : NSELect command. If INST : COUP ALL is
programmed, all commands are sent to all output phases. This command affects set voltage
and queries Measurement data. For example, if “INST : COUP ALL ” and “INST : NSEL 2”
and “Meas : V?” are programmed, the AC source will return ∅2‘s measured voltage.
INST : NSEL selects phase by its number, and INST : SEL refers to it by its name.
ORELay ON | OFF Set output relay on (closed) or off (open)
This command sets output relay on/off.
ON sets the output relay of the AC source on (closed).
OFF sets the output relay of the AC source off (open).
OUTPut
[ : STATe] <bool> Enable/disable the output of the AC source
: PROTection
: CLEar Reset protection status
: DELay <n> Set the delay time of protection
OUTPut [ : STATe] ON | OFF
Query syntax OUTPut?
Return parameters ON | OFF
This command enables or disables the output of the AC source. Disable output is to set an
output voltage amplitude at 0 Volt.
OUTPut : PROTection : CLEar
This command clears the latch that disables the output when an overcurrent (OC),
overtemperature (OT) or overpower (OP) is detected. All conditions which have generated
the fault must be removed before the latch is cleared.
OUTPut : PROTection : DELay <NR2>
Query syntax OUTPut : PROTection : DELay?
Parameter 0.0 to 100.0
Return parameters <NR2>
