Chapter1 SCPI Introduction

1.1 Overview

SCPI  is  short  for  Standard  Commands  for  Programmable  Instruments  which
defines a communication method of bus controller and instrument. It is based
on ASCII and supply for testing and measuring instruments. SCPI command is
based  on  hierarchical  architecture  which  also  known  as  tree  system.  In  this
system,  Relevant  Command  is returned to  a  common  node  or  root,  so  that  a
subsystem is formed. A part of OUTPut subsystem is listed below:

OUTPut:

• SYNC {OFF|0|ON|1}

• SYNC:

– MODE {NORMal|CARRier}

– POLarity {NORMal|INVerted}

OUTPut is the root class keyword, SYNC is the second keyword, MODE and
POLarity are the third keyword. Colon(:) is used for separating the command
keyword and the next level keyword.

1.2 Command Type of SCPI

SCPI has two types of commands, common and subsystem.

⚫

Common commands generally are not related to specific operation but to

controlling overall

instrument

functions, such as reset, status, and

synchronization. All commoncommands consist of a three-letter mnemonic
preceded by an asterisk:

*RST *IDN? *SRE 8

.

⚫

Subsystem commands perform specific instrument functions. They are

organized into an inverted tree structure with the "root" at the top. The
following figure shows a portion of a subsystem command tree, from which
you access the commands located along the various paths.

Multiple Commands in a Message

Multiple  SCPI  commands  can  be  combined  and  sent  as  a  single
message  with  one  message  terminator.  There  are  two  important
considerations  when  sending  several  commands  within  a  single
