1. Overview

This chapter means to give an overall description of the S3331 programming and SCPI, following content is included:

 Overview of S3331 programming
 SCPI introduction

 Format
 Symbol
 Parameter

 Command

1.1. S3331 Programming

S3331 supports remote access via LAN or USB port. All programming commands are sent as ASCII strings for easy programming and
development.

S3331 provide following remote control functions:

 Instrument configuration
 Measurement
 Data access (status/measurement data)
 Print

1.2. Introduction to the S CPI command

SCPI (Standard Commands for Programmable Instrument) is a standard instruction set of programmable instrument on IEEE 488.2. The
SCPI command is divided into two parts: the IEEE 488.2 common command and the SCPI instrument specific control command.

The common command is a command that the instrument specified by IEEE 488.2 must support, and its syntax and semantics follow the
requirements of IEEE 488.2. Common commands are independent of measurement and are used to control reset, self-test, and state
operations. Refer to the IEEE 488.2 section for an introduction to the SCPI common command.

SCPI instrument specific control commands for measuring, access to data and other operations, including all measurement functions and
some calculation functions.

1.2.1. Command format

The SCPI command is a tree hierarchy, including multiple subsystems, each consisting of a root key and one or more hierarchical
keywords. The command line begins with a colon " : "; the keywords are separated by a colon " : " followed by an optional parameter; the
question mark " ? " Is appended to the command line to indicate that the function is queried; commands and parameters are separated
by a space " ".

 Example

:CALCulate:BANDwidth:NDB <rel_ampl>
:CALCulate:BANDwidth:NDB?

6

Tel: [phone] Email: [e-mail]

www.salukitec.com

CALCulate is the root of the command, BANDwidth and NDB are the second and third level keywords. The command line begins with a
colon "," and separates the keywords at all levels. <Rel_ampl> represents the settable parameter; the question mark "?" Indicates the
query; the command: CALCulate: BANDwidth: NDB and the parameter <rel_ampl> is separated by a space “ “.

In some commands with parameters, usually with a comma ", " separate multiple parameters, such as:

: SYSTem: DATE <year>, <month>, <day>

1.2.2. Symbol Description

The following four symbols are not the contents of the SCPI command, but are usually used to describe the parameters in the command.

1.2.2.1. Braces {}

The parameters in braces are optional, can be empty, or can be set one or more parameters.

 Example

[:SENSe]:CORRection:CSET<n>:DATA <freq>,<rel_ampl>{,<freq>,<rel_ampl>}

In {,<freq>,<rel_ampl>} the frequency and amplitude can be omitted, or se t one or more pairs of frequency/amplitude parameters.

1.2.2.2. Vertical bar |

The vertical bar is used to separate multiple parameter options, and one of the parameters must be selected when execute the
command.

 Example

: DISPLAY: MENU: STATe OFF | ON | 0 | 1

The available command parameters are "OFF", "ON", "0" or "1", one of them must be selected.

1.2.2.3. Square brackets []

The contents in the square brackets (command keywords) are optional and can be omitted.

 Example

[: SENSe]: CORRection: OFFSet [: MAGNitude]?

This command equals to following 3 commands:

: CORRection: OFFSet?
: CORRection: OFFSet: MAGNitude?
: SENSe: CORRection: OFFSet?

1.2.2.4. Triangle brackets <>

The parameters in the triangle brackets must be a valid value.

 Example

: DISPlay: BRIGtness <integer>
: DISPlay: BRIGtness 10

1.2.3. Parameter Type

7

Tel: [phone] Email: [e-mail]

www.salukitec.com

The parameters contained in the commands described in this manual can be classified into the following six types: Boolean, keyword,
integer, continuous real, discrete, ASCII string.

1.2.3.1. boolean

The parameter values are "OFF", "ON", "0" or "1".

 Example

: DISPlay: MENU: STATe OFF | ON | 0 | 1

1.2.3.2. keywords

The value of the parameter is the value listed.

 Example

: DISPlay: AFUnction: POSition BOTTom | CENTer | TOP

The parameters are "BOTTom", "CENTer" or "TOP".

1.2.3.3. Integer

Unless otherwise noted, the parameter can take any integer value within the valid range. Note that this time, please do not set the
parameters to decimal format, otherwise an exception will occur.

 Example

: DISPlay: BRIGtness <integer>

The parameter <integer> is any integer in the range 0 to 255.

1.2.3.4. Continuous real type

Any continuous real parameters is allowed in the effective range of precision requirements (usually the default accuracy is six digits after
decimal point).

 Example

: CALCulate: BANDwidth: NDB <rel_ampl>
The parameter <rel_ampl> desires a real number between -100 and 100.

1.2.3.5. Discrete

Parameters can only take from the specified values, and these values are not continuous.

 Example

: CALCulate: MARKer <n>: MAXimum: MAX

The parameter <n> can only be 1, 2, 3, or 4.

1.2.3.6. ASCII string

The parameter value is a combination of ASCII characters.

 Example

: SYSTem: DATE <year>, <month>, <day>

8

Tel: [phone] Email: [e-mail]

www.salukitec.com

The parameter is the set date format string.

1.2.4. Command abbreviation

All commands are case insensitive, user can use uppercase or lowercase. Meanwhile if abbreviations to be used, users must type in all
the capital letters in the command format.

 Example

: CALCulate: BANDwidth: NDB?

Can be abbreviated as :

: CALC: BAND: NDB?
