Sets or reads the contents of the Questionable Event Enable Register of the status model. When set, bits in this register enable the corresponding bits in the Questionable Event Register and can set the QSM bit in the Status Byte Register.

:STAT:QUES:ENAB #b0010000000000000

Reads and clears the Questionable Instrument Event Register of the status model.

Sets or reads the contents of the Questionable Instrument Event Enable Register of the status model. When one of these bits is set and the corresponding bit in the Questionable Instrument Event Register is set, the ISUM bit in the Questionable Event Register is set.

:STAT:QUES:INST:ENAB #b0000000000000010

Reads the Questionable Instrument Summary Event Register of the status model and clears the register. The instrument returns a decimal value equal to the binary-weighted sum of all bits set in the register.

:STAT:QUES:INST:ISUM?

Sets or reads the contents of the Questionable Instrument Summary Event Enable Register of the status model. When bits are set and the corresponding bit in the QISER is set, bit 1 in the Questionable Instrument Event Register is set.

:STATus:QUEStionable:INSTrument:ISUMmary:ENABle <n>
:STATus:QUEStionable:INSTrument:ISUMmary:ENABle?

Reads the contents of the Questionable Instrument Summary Condition Register of the status model.

:STAT:QUES:INST:ISUM:COND?

Enables or disables the autozero function. When autozero is disabled, reference and internal temperature measurements are not performed, increasing measurement speed.

:SYST:AZER OFF

Turns the error beeper on or off. When enabled, a beep signals that an error has happened.

:SYSTem:BEEPer:ERRor ON Enable the error beeper.

Causes remote control to transfer to the present interface. When sent by one interface, the present active interface is blocked and the sending interface becomes active.

SYSTem:COMMunication:ABORt

Specifies the LAN configuration for the instrument. Automatic configuration uses DHCP first and then DLLA; manual configuration lets you define the IP address, subnet mask, and default gateway.

:SYSTem:COMMunication:LAN:CONFigure AUTO
:SYSTem:COMMunication:LAN:CONFigure MANual,"<IPaddress>"
:SYSTem:COMMunication:LAN:CONFigure MANual,"<IPaddress>","<NETmask>"
:SYSTem:COMMunication:LAN:CONFigure MANual,"<IPaddress>","<NETmask>","<GATeway>"

Queries the LAN MAC address of the instrument. The MAC address is returned as a hexadecimal character string with colons separating the octets.

:SYSTem:COMMunication:LAN:MACaddress?

Sets or queries the instrument calendar date. The query returns the present date in the format <year>,<month>,<day>.

:SYST:DATE 2014, 5, 12 Set the system date to May 12, 2014.

Reads the oldest error message from the event log. The error queue is FIFO and holds up to 64 messages; reading this command clears the returned error from the queue.

:SYST:ERR?

Clears the error queue and removes all messages from it.

Reads and clears the oldest error code. The command returns the numeric code of the last error in the event log, and the error is cleared from the queue after being read.

:SYST:ERR:CODE? Returns the error number of the last error in the error queue.

Returns the number of errors in the error queue. It does not clear the errors from the queue.

:SYST:ERR:COUN?

Saves all event log entries since the last clear command to a USB flash drive. The .csv extension is automatically added to the filename.

:SYST:EVEN:SAVE "error_log"

Sets the GPIB address of the instrument. The address can be set from 1 to 30 and is saved in nonvolatile memory.

:SYST:GPIB:ADDR 26
:SYST:GPIB:ADDR?

Enables or disables the key click sound. When enabled, front-panel key presses produce a sound signaling that a key has been pressed.

:SYSTem:KCLick ON Enable the key clicks.

Takes the instrument out of remote operation and restores the front-panel controls.

Returns the line frequency that was automatically detected when the instrument was turned on. The line frequency can be 50 Hz or 60 Hz.

:SYST:LFR? Return the line frequency.

Sets a remote interface to lock mode. When password protection is enabled, sending this command disables the remote interface and prevents SCPI commands from that interface except :SYSTem:LOCal.

Sets the protection mode for the remote connection. When set to ALL, a password is required before sending :SYSTem:PASSword:LOCK or :SYSTem:PASSword:UNLock.

:SYST:PASS:MODE ALL Enable the password protection.

Sets a new password for the remote connection. The instrument keeps using the old password until the change command has finished executing.

:SYST:PASS:NEW "admin","123456" Change the password of the instrument to 123456

Enables a remote interface. When the remote interface is locked, sending the command with the correct password releases it; a wrong password causes error 509, "System password not correct."

:SYST:PASS:UNL "admin"

Enables or disables default setup loading. When set to On, the power setup loads setup 1 immediately after power-on.

:SYST:POS:STAT ON
:SYST:POS:STAT?

Returns the instrument to the factory default conditions and erases all user data stored in nonvolatile memory. It does not influence the status structure registers or error queue, and it resets the GPIB and IP addresses to default settings.

:SYST:PRES

Locks out the front-panel controls so the instrument can only be controlled through the remote interface.

:SYST:RWLock

Sets the absolute time of the instrument. The query returns the present timestamp in the format <hour>,<minute>,<second>.

:SYST:TIME 5, 51, 30

Queries the present SCPI standard version.

:SYST:VERS?
