SCPI Introduction

SCPI Introduction

This chapter describes in detail the command types, parameter types and other
related information about SCPI.

Remote Interface Connections

1.1 Overview

SCPI is short for Standard Commands for Programmable Instruments which de-

fines 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 sys-

tem, Relevant Command is returned to a common node or root, so that a sub-

system 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 synchroni-

zation. All common commands consist of a three-letter mnemonic preceded

by an asterisk:

*RST *IDN? *SRE 8
