5.3.1 Interface Commands (Alphabetical Listing)
*CLS
Clear Interface Command
Input: *CLS[term]
Remarks:
Clears the bits in the Status Byte Register and Standard Event Status Register and terminates all
pending operations. Clears the interface, but not the instrument. The related instrument command
is *RST.
*ESE
Standard Event Status Enable Register Command
Input: *ESE <bit weighting>[term]
Format: nnn
Remarks: The Standard Event Status Enable Register determines which bits in the Standard Event Status
Register will set the summary bit in the Status Byte. This command programs the enable register using
a decimal value that corresponds to the binary-weighted sum of all bits in the register. Refer to
Paragraph 5.1.4.2.1.
