11.3. IEEE 488.2 common commands

Introduction

The common commands are defined by the IEEE 488.2 standard. They are operational on all instruments which are specified IEEE 488.2. They command basic functions such as: identification,

reset,

configuration reading,

reading of event and status register,

reset of event and status register.

If a command containing one or several directories has been received, and if a common command has been stacked up, then the instrument stays in this directory and execute normally the commands.
