28 Command Reference Chapter 3
Common Command Reference
This section describes the IEEE-488.2 Common Commands that can be used to
program instruments in the mainframe. Commands are listed alphabetically (the
following table shows the Common Commands listed by functional group). For
additional information on any Common Commands, refer to the IEEE Standard
488.2-1987.
*CLS
Clear Status Command. The *CLS command clears all status registers (Standard
Event Status Register, Standard Operation Event Status Register, Questionable Data
Event Register) and the error queue for an instrument. This clears the corresponding
summary bits (bits 3, 5, & 7) and the instrument-specific bits (bits 0, 1, & 2) in the
Status Byte Register. *CLS does not affect the enabling of bits in any of the status
registers (Status Byte Register, Standard Event Status Register, Standard Operation
Enable Status Register, or Questionable Data Enable Status Register). (The SCPI
command STATus:PRESet does clear the Standard Operation Status Enable and
Questionable Status Enable registers.) *CLS disables the Operation Complete
function (*OPC command) and the Operation Complete Query function (*OPC?
command).
