Command

 

 

 

Command

ASTS?

 

This command reads the contents of the accumulated status

 

STAT:OPER?

 

 

register, which stores any bit condition entered in the status

 

STAT:QUES?

 

 

register since the accumulated status register was last read,

 

*ESE?

 

 

regardless of whether the condition still exists.

 

 

 

 

Data Representation: ZZZZD

 

 

CLR

 

This command initializes the dc source to the power-on state. It

 

*RST

 

 

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

 

 

 

 

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

 

 

 

 

message.

 

 

DC 0 1

 

Only applies to units with Relay Option 760. This command

 

OUTP:STAT[:NOR]

 

 

enables or disables the output without affecting the state of the

 

0 1 OFF ON

 

 

output relays.

 

 

 

 

Initial condition: DC 1

 

 

DLY <n>

 

This command programs the delay time between the programming

 

OUTP:PROT:DEL

 

 

of an output change that produces a CV, CC, or an UNREG

 

 

 

 

condition, and the recording of that condition by the status

 

 

 

 

registers. This can be used to prevent false triggering of the

 

 

 

 

OverCurrent Protection feature (OCP).

 

 

 

 

Initial delay: 0.08s (Normal); 0.008s (Fast).

 

 

DSP 0 1

 

This command enables or disables the dc source’s front panel

 

DISP 01OFFON

 

 

display.

 

 

 

 

Initial condition: DSP 1

 

 

ERR?

 

This command determines the type of programming error detected

 

SYST:ERR?

 

 

by the dc source. A remote programming error sets the ERR bit in

 

 

 

 

the status register, which can be enabled by UNMASK to request

 

 

 

 

service.

 

 

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.

 

 

 

 

Data Representation: ZZZZD

 

 

ID?

 

This command causes the dc source to report its model number

 

*IDN?

 

 

and any options that affect the dc source’s output.

 

 

 

 

Data Representation: Agilent663XA

 

 

IOUT?

 

This command measures and returns the actual output current.

 

MEAS:CURR?

 

 

Data Representation: SD.DDDD

 

 

ISET <n>

 

This command programs the output current. See Table 4-3 for the

 

CURR

 

 

programming range of this command.

 

 

 

 

Initial condition: see Table B-1

 

 

OCP 0 1

 

This command enables or disables the dc source’s overcurrent

 

CURR:PROT:STAT

 

 

protection. If this function is enabled and the dc source goes into

 

0 1 OFF ON

 

 

CC mode, the output of the dc source is disabled. Initial condition:

 

 

 

 

OCP 0

 

 

OUT 0 1

 

This command enables or disables the dc source’s output. The dc

 

OUTP:STAT

 

 

source will be able to implement commands even while the output

 

0 1 OFF ON

 

 

is disabled. Initial condition: OUT 1
