Command structure
TH2883 series has two types of commands: GPIB common commands and SCPI commands. The
GPIB common commands are defined in IEEE std.488.2-1987, and these commands are common
for all devices. Not all GPIB commands are supported by the TH2883 series. The SCPI commands
are used to control all of the TH2883’s functions. The SCPI commands are tree-structured and
three-level deep. (The highest level commands are called the subsystem commands in this manual.)
So the lower level commands are legal only when the subsystem commands have been selected. A
colon (:) is used to separate the higher level commands and the lower level commands. See Figure
8-1 for a sample.

Basic rules of commands structure:
Letter case (upper and lower) is ignored.
For example: COMP:AREA ON = comp:area on = Comp:aRea On
Space (_ indicates a space) must not be placed before and/ or after a colon (:).
For example:
COMP _:_ AREA ON
COMP:AREA ON
Space is used to partition off command and parameter. Commands locate before space and
their corresponding parameters put after space.
For example: COMP:AREA ON, AREA is command, ON is parameter.
Some command has no parameter.
For example: Trigger command-TRIG, Standard waveform choosing command:
SWAVE:CHOOSE
The command can be completely spelled out or in abbreviated type. (The rules of command
abbreviation are described later in this section, and abbreviation is spelling out in upper letter
