†These are specified minimum and maximum values, with the calibration factor (:INPut:OFFSet) set to zero. Actual values depend on the instrument, and the calibration factor.

‡ These values are interdependent

8.3 The Common Commands

The IEEE 488.2 standard has a list of reserved commands, called common commands. These are the commands that start with an asterisk. Some of these commands must be implemented by any instrument using the standard, others are optional. This section describes the implemented commands.

Common Status Information

There are four registers for the common status information. Two of these are status-registers and two are enable-registers. These registers conform to the IEEE Standard 488.2-1987. You can find further descriptions of these registers under “*ESE” on page 95, “*ESR?” on page 96, “*SRE” on page 101, and “*STB?” on page 102.
