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. The s e 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 C ommand
*SRE Service Request Enable Command
*SRE? Service Request Enable Query
*STB? Read Status Byte Query
*TST? Self-Test Query
*WAI Wait-to-Continue
C ommand
*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 <da ta>
The
Standard Event Status Enable (ESE) command sets the Standard Event Status Enable
Register. The variable <data> 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
