SCPI Introduction

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:

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 message:

⚫ Use a semicolon to separate commands within a message.

⚫ Head paths influence how the instrument interprets commands.

We consider the head path as a string which will be inserted in front of

every command of a message. As for the first command of a message, the

head path is a null string; for each subsequent command, the head path is

a string which is defined to form the current command until and including

the head of the last colon separator. A message with two combined

commands:

CURR:LEV 3;PROT:STAT OFF

Page 16 of 137

SCPI Introduction

DELAY. In the short form, the header has only the first three or four letters, such

as VOLT, STAT and DEL.

Query indicator

Following a header with a question mark turns it into a query (VOLTage?,

VOLTage:PROTection?). If a query contains a parameter, place the query

indicator at the end of the last header (VOLTage:PROTection?MAX).

Message unit separator

When two or more message units are combined into a compound message,

separate the units with a semicolon (STATus:OPERation?;QUEStionable?).

Root specifier

When it precedes the first header of a message unit, the colon becomes the root

specifier. It tells the command parser that this is the root or the top node of the

command tree.

Message terminator

A terminator informs SCPI that it has reached the end of a message. Three

permitted message terminators are:

⚫ newline (<NL>), decimal 10 or hexadecimal 0X0A in ASCII.

⚫ end or identify (<END>)

⚫ both of the above (<NL><END>).

In the Examples of this guide, there is an assumed message terminator at the end

of each message.

Command execution rules

⚫ Commands execute in the order that they are presented in the program

message.

⚫ An invalid command generates an error and, of course, is not executed.

⚫ Valid commands that precede an invalid command in a multiple command

program message are executed.

⚫ Valid commands that follow an invalid command in a multiple command

program message are ignored.

1.4 Response Data Type

Character strings returned by query statements may take either of the following

forms, depending on the length of the returned string:

⚫ <CRD>: character response data. Permits the return of character strings.

⚫ <AARD>: arbitrary ASCII response data. Permits the return of undelimited

7-bit ASCII. This data type has an implied message terminator.

⚫ <SRD>: string response data. Returns string parameters enclosed in double

quotes.

⚫ <Block>: arbitrary block data.

Response messages

A response message is the message sent by the instrument to the computer in

Page 18 of 137

SCPI Introduction

⚫ Vertical stripes (|) separate several parameter options with given command

strings. For Example, {VPP|VRMS|DBM} indicates that you may assign

"APP", "VRMS" or "DBM" in the above commands. Vertical stripes are not

sent along with command strings.

⚫ Angle brackets (< >) in the second Example indicates that a value must be

assigned to the parameter in the brace. For Example, the parameter in the

angle bracket is <frequency> in the above syntax statements. Angle brackets

are not sent along with command strings. You must assign a value (such as

"FREQ:CENT 1000") to the parameter, unless you select other options

displayed in the syntax (such as "FREQ:CENT MIN").

⚫ Some syntax elements (such as nodes and Parameter) are included in

square brackets ([ ]). It indicates that these elements can be selected and

omitted. Angle brackets are not sent along with command strings. If no value

is assigned to the optional Parameter, the instrument will select a default

value. In the above Examples, "SOURce[1|2]" indicates that you may refer to

source channel 1 by "SOURce" or "SOURce1" or "SOUR1" or "SOUR". In

addition, since the whole SOURce node is optional (in the square bracket),

you can refer to the channel 1 by omitting the whole SOURce node. It is

because the channel 1 is the default channel for SOURce language node. On

the other hand, if you want to refer to channel 2, "SOURce2" or "SOUR2"

must be used in the program line.

Colon (:)

It is used to separate key words of a command with the key words in next level.

As shown below:

APPL:SIN 455E3,1.15,0.0

In this Example, APPLy command assigns a sine wave with frequency of 455 KHz,

amplitude of 1.15 V and DC offset of 0.0 V.

Semicolon (;)

It is used to separate several commands in the same subsystem and can also

minimize typing. For Example, to send the following command string:

TRIG:SOUR EXT; COUNT 10

has the same effect as sending the following two commands:

TRIG:SOUR EXT

TRIG:COUNT 10

Question mark (?)

You can insert question marks into a command to query current values of most

Parameter. For Example, the following commands will trigger to set the count as

10:

TRIG:COUN 10

Then, you may query count value by sending the following command:

TRIG:COUN?

You may also query the allowable minimum or maximum count as follows:

TRIG:COUN?MIN

TRIG:COUN?MAX

Page 20 of 137

SCPI Introduction

MIN and MAX are the minimum and maximum finite number. Within the range

of the parameter definition, DEF is the default of the parameter.

⚫ Discrete parameter

Discrete parameter are used for settings with limited number of programming

values (such as IMMediate, EXTernal or BUS). They can use short and long

format like key words of commands. They may be expressed in both upper

and lower case. The query response always returns uppercase Parameter in

short format. The following commands require discrete parameter in voltage

unit:

[SOURce[1|2]:]VOLTage:UNIT {VPP|VRMS|DBM}

⚫ Boolean parameter

Boolean parameter refer to true or false binary conditions. In case of false

conditions, the instrument will accept "OFF" or "0". In case of true conditions,

the instrument will accept "ON" or "1". In query of Boolean settings, the

instrument will always return "0" or "1". Boolean parameter are required by

the following commands:

DISPlay {OFF|0|ON|1}

⚫ ASCII string parameter

String parameter may actually include all ASCII character sets. Character

strings must start and end with paired quotation marks; and single quotation

marks or double quotation marks are both allowed. Quotation mark

separators may also act as one part of a string, they can be typed twice

without any character added between them. String parameter is used in the

following command:

DISPlay:TEXT <quoted string>

For Example, the following commands display message of "WAITING..."

(without quotation marks) on the front panel of the instrument.

DISP:TEXT "WAITING..."

Single quotation marks may also be used to display the same message.

DISP:TEXT 'WAITING...'

– <SPD>: string program data. String parameters enclosed in single or

double quotes.

– <CPD>: character program data.

1.7 Remote Interface Connection

IT8200 series electronic load are equipped with three communication interfaces

as standard: USB, LAN and CAN, and two optional interfaces: RS232 and GPIB.

Users can choose any one to realize communication with the computer. For

detailed introduction of remote interface connection, please refer to the content in
