.5.1 IEEE 488.2 Commands
he purpose of IEEE488.2 commands is to provide management and data communication instructions for the system by
g a set of “*” commands (an asterisk followed by a three character code). These commands allow device control and
onitoring, and are e basis for some of the commands of the SCPI STATus subsystem (see Section 5.5.12).

Clear Status command. This command resets the SCPI status registers (Questionable Status and
Operation Status), the error queue, the IEEE488.2 Status Byte (STB) and Standard Event Status
(ESR) registers, and the mea
Syntax: *CLS
Argument: None
*ESE
Description: Set or return the Standard Event Status Enable Register. The mask value in this register is used to
enable bits of the Standard Event Status Register that are or’ed together to form the ESB summary
bit in the instrument Status Byte. When a mask bit is set, and the corresponding ESR bit goes
true, an SRQ will be generated, provided the Event Status Summary bit (ESB, bit 5) is enabled in
the SRE register. No SRQ can be generated for that condition if the mask bit is cleared. To clear
the entire Standard Event Status Enable Register, send *ESE = 0. See the *ESR command for bit
assignments. This register is not cleared by *CLS, *RST or DCLR.
Syntax: *ESE <numeric value>
