Chapter 8 Command reference
Command structure
PT50xx 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 PT50xx series. The SCPI commands
are used to control all of the PT50xx‟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
