Section 7 SCPI Outline

7.1 Outline

SCPl is a device command language defined by the SCPI consortium and is independent from the hardware. SCPI is designed to shorten the period for development of automatic measuring instrument (ATE). For this reason, the programming environments such as the device control and data handling are made consistent. Moreover, it is characterized by its ability to perform totally even control of devices of the same model as well as devices of different models compatible with each other that are equipped with the same functions.

7-2

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

7.2 Command Structure

The SCPI command form a hierarchical structure. Commands are divided into groups, each of which consists of com mands of similar functions, and each group forms a hierarchical structure called the subsystem. This specification expresses these subsystems by the command tree as shown below. SCPI allows the same headers to be present in a tree and the difference in the location of the header corresponds to the difference in the function. Therefore, a command must be described in a full path up to the header to be used.

BRATe — BRATe? EQUAlizer EQUAlizer?

7.3 Command Description Method

SOURce : TELecom : BRATe <brate> SOURce ; TELecom ; BRATe? SOURce ; TELecom : EQUAlizer <boolean> SOURce : TELecom : EQUAlizer?

Fig. 7-2 Example of SCPI Commands

The command tree shown in the previous section consists of the commands shown above. 1 lie section below provides explanations of the stipulations concerning descriptions of commands.

<Command format>

A command begins with a colon ( : ). Or, a command is structured by concatenating headers with a colon ( : ).

<Form of header abbreviation>

Headers come in short and long forms.

The short form signifies an abbreviated form of the long form.

A command is interpreted as the same command whether it is expressed in the short or long form. (The short and long form can be mixed.)

This specification uses the uppercase and lowercase characters to distinguish the short and long forms. (The section

expressed in uppercase characters refers to the short fomi.) However, the uppercase and lowercase characters are not distinguished when they are actually used.

Example:

Long form Short form Long+short form

> ; SOURce ; TELecom ; BRATe M9953

> sour : TEL : BRAT M9953

> Sour : TELecom : BRAT M9953

<Option node>

The section in the brackets ( [ and ] ) expresses the option node. The header enclosed by the brackets ( [ and ] ) can be

abbreviated, and the abbreviated and non-abbreviated forms of a header are interpreted as the same command.

Example:

When a header is not abbreviated > : DISPlay : DSELect: NAME "SETup"

When a header is abbreviated > : DISPlay : DSELect: "SETup"

<Header separator>

At least one space character is always inserted between a command and a parameter. Two or more parameters are

separated by a comma ( , ).

7-4

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

7.4 Compounding Commands

Commands can be compounded by using semi-colon ( ; ) as shown by the example below. The second command is also referenced as the command located at the same level as the lowest hierarchical level of the first command.

For this reason, the second command can be described in a full path as shown by Example 1. Flowever, as Example 2

shows, headers located in the layer above Type can also be abbreviated.

Example 1: > : SENSe : TELecom : PATTem ; TYPE UWORdlb ; : SENS : TELecom : PATTem : UWORd "1100110011001100"

Example 2:

> : SENSe ; TELecom : PATTem : TYPE UWORdlb ; UWORd "1100110011001100"

An explanation is given for commands other than sequential commands every time they come up.

When a set value by a program command causes set values for other items to become unacceptable, they will be changed to allowed values. Moreover, the measurement starts again when settings are modified during measurement. See the details of the operation method in this operation manual for conditions to change set values for other items and to execute restart.

The following section shows examples of descriptions of commands.

<Program command>

When a restriction on command use exists, an item called the restriction is added to the example below.
