ARPS Command

Description Similar SCPI
Command
UNMASK?
This command reads which bits in the status register have been
enabled as fault conditions. The decimal equivalent of the total bit
weight of all enabled bits is returned.
STAT:OPER:ENAB?
STAT:QUES:ENAB?
ESE
FAULT?
This command reads which bits have been set in the fault register.
A bit is set in the fault register when the corresponding bit in the
status register changes from inactive to active AND the
corresponding bit in the mask register has been enabled. The fault
register is reset only after it has been read. The decimal equivalent
of the total bit weight of all enabled bits is returned.
STAT:OPER?
STAT:QUES?
*ESE
SRQ OFF
SRQ 0
SR*Q ON
SRQ 1
These commands enable or disable the power supply's ability to
request service from the controller for fault conditions. UNMASK
defines which conditions are defined as faults.
Initial condition: SRQ OFF
*SRE
SRQ?
This command reads the SRQ setting.
*SRE?
CLR
This command initializes the power supply to the power-on state.
It also resets the PON bit in the serial poll register. The command
performs the same function as the Device Clear (DCL) interface
message.
*RST
ERR?
This command determines the type of programming error detected
by the supply. A remote programming error sets the ERR bit in the
status register, which can be enabled by UNMASK to request
service.
SYST:ERR?
TEST?
This command causes the power supply to run selftest and report
any detected failures.
*TST?
ID?
This command causes the power supply to report its model number
and any options that affect the supply's output.
*IDN?
SYST:LANG
This command causes the alternate language to become active and
to be stored in nonvolatile memory. In this case, the commands are
equivalent. After being shut off, the power supply will resume in
the last-selected language when power is restored. The parameter
must be either COMP or TMSL, not SCPI.
