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. The tunable laser source implements all the necessary commands,
and some optional ones. This chapter 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 nd further descriptions of these registers
under \*ESE", \*ESR?", \*SRE", and \*STB?".
The following gure shows how the registers are organized.
