2. SCPI Status Registers
2.1. Command introduction
SCPI commands can be divided to common and subsystem commands.
Common commands are defined by the IEEE 488.2 standard to perform common interface
functions. They begin with an * and consist of three letters (command) or three letters and
a ? (query).
Subsystem commands are specific to 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.

2.2. Program syntax
FTG series programmable DC power supply SCPI commands are inherited and expanded
from IEEE488.2 standards. SCPI commands are constructed with keyword, seperator,
paramter and terminator. Below is an example,
CURRent:STATic:L1 10.0
In this command, CURRent, STATic, L1 are command keywords, “:” and space character are
seperator, 10.0 is parameter (some commands have multiple parameters seperated with
comma “,”), A <carriage return> at the end of this command is the command terminator.
Throughout this document, the following conventions are used for the SCPI command
syntax:
