Interface Commands (Alphabetical Listing)

*CLS
Clear Interface Command
Input: *CLS[term]
Clears the bits in the Status Byte Register and Standard Event Status Register and terminates all
Remarks:
pending operations. Clears the interface, but not the instrument. The related instrument command
is *RST.
*ESE
Standard Event Status Enable Register Command
*ESE <bit weighting>[term]
Input:
nnn
Format:
The Standard Event Status Enable Register determines which bits in the Standard Event Status
Remarks:
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.
