IEEE 488.2 Required Commands
*CLS
Description This command sets the contents of the Standard Event Register
(ESR), the Status Byte Register (STB), and the Error Queue
(ERR) to zero. This command is commonly used to clear the
status registers before enabling SRQ. Note that the output
queue, Standard Event Status Enable Register (ESE), and
Service Request Enable Register (SRE) are not affected.
Syntax *CLS
Note The CLR command is equivalent to the *CLS command. Both
give the same result.
*ESE
Description This command is used to set bits in the Standard Event Status
Enable Register (ESE) to a new value (default value is 255). The
contents of the ESE register are logically ANDed with the ESR
register. A non zero result will set the Event Summary Bit (ESB)
of the Status Byte Register. This command is useful for selecting
which events may generate an SRQ.
Syntax *ESE<wsp><value>
Parameter The <value> parameter must be between 0 and 255.
*ESE?
Description This query reads the contents of the Event Status Register.
Syntax *ESE?
Response Binary integer with a value between 0 and 255.
