ARPS Command1

Description

Similar SCPI

 

 

Command

UNMASK?

This command reads which bits in the status register have been

STAT:OPER:ENAB?

 

enabled as fault conditions. The decimal equivalent of the total bit

STAT:QUES:ENAB?

 

weight of all enabled bits is returned.

ESE

 

 

 

FAULT?

This command reads which bits have been set in the fault register.

STAT:OPER?

 

A bit is set in the fault register when the corresponding bit in the

STAT:QUES?

 

status register changes from inactive to active AND the

*ESE

 

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.

 

 

 

 

SRQ OFF

These commands enable or disable the power supply's ability to

*SRE

SRQ 0

request service from the controller for fault conditions. UNMASK

 

SR*Q ON

defines which conditions are defined as faults.

 

SRQ 1

Initial condition: SRQ OFF

 

 

 

 

SRQ?

This command reads the SRQ setting.

*SRE?

CLR

This command initializes the power supply to the power-on state.

*RST

 

It also resets the PON bit in the serial poll register. The command

 

 

performs the same function as the Device Clear (DCL) interface

 

 

message.

 

 

 

 

ERR?

This command determines the type of programming error detected

SYST:ERR?

 

by the supply. A remote programming error sets the ERR bit in the

 

 

status register, which can be enabled by UNMASK to request

 

 

service.

 

 

 

 

TEST?

This command causes the power supply to run selftest and report

*TST?

 

any detected failures.

 

 

 

 

ID?

This command causes the power supply to report its model number

*IDN?

 

and any options that affect the supply's output.

 

 

 

 

SYST:LANG

This command causes the alternate language to become active and

SYST:LANG

 

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.
