3. IEEE-488 Interface Commands
IEEE Mandated Commands
The required common commands are IEEE-488.2 mandated commands that are defined
in the IEEE-488.2 standard and must be implemented by all SCPI compatible
instruments. These commands are identified by the asterisk (*) at the beginning of the
command keyword. These commands are used to control instrument status registers,
status reporting, synchronization, and other common functions.
Commands declared mandatory by IEEE 488.2.
*CLS Clear Status Command
*ESE Standard Event Status Enable Command
*ESE? Standard Event Status Enable Query
*ESR? Standard Event Status Register Query
*IDN? Identification Query
*OPC Operation Complete Command
*OPC? Operation Complete Query
*RST Reset Command
*SRE Service Request Enable Command
*SRE? Service Request Enable Query
*STB? Read Status Byte Query
*TST? Self-Test Query
*WAI Wait-to-Continue Command
*CLS
The Clear Status (CLS) command clears the status byte by emptying the error queue and
clearing all the event registers including the Data Questionable Event Register, the
Standard Event Status Register, the Standard Operation Status Register and any other
registers that are summarized in the status byte.
*ESE
The Standard Event Status Enable (ESE) command sets the Standard Event Status
Enable Register. The variable represents the sum of the bits that will be enabled.
Range 0–255
Remarks The setting enabled by this command is not affected by signal generator preset
or *RST. However, cycling the signal generator power will reset this register to zero.
*ESE?
The Standard Event Status Enable (ESE) query returns the value of the Standard Event
Status Enable Register.
*ESR?
The Standard Event Status Register (ESR) query returns the value of the Standard Event
Status Register.
NOTE: Reading the Standard Event Status Register clears it
Remarks The Register is not affected by signal generator preset or *RST. However,
cycling the signal generator power will reset this register to zero.
