This instrument complies with the rules and conventions of the present SCPI version (see
SYSTem:VERSion?).
SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command
language designed for test and measurement instruments. SCPI has two types of commands,
common and subsystem.
IEEE 488.2 Common commands are defined by the IEEE 488.2 standard to perform common interface
functions such as reset, status, and synchronization. All common commands consist of a three-letter
mnemonic preceded by an asterisk: *RST *IDN? *SRE 8.
Subsystem commands perform specific instrument functions. They can be a single command or a
group of commands. The groups are comprised of commands that extend one or more levels below
the root. Subsystem commands are arranged alphabetically according to the function they perform.
The following figure shows a portion of a subsystem command tree, from which you access the
commands located along the various paths. Some [optional] commands have been included for clarity

Keywords
Keywords, also referred to as headers, are instructions recognized by the instrument. Common
commands are also keywords.
