Getting Started

This manual contains information on the Standard Commands for Programmable Instruments (SCPI) and IEEE 488.2 Common Commands you can use to program your MTS400 S optional commands that control the optional interface cards.

Connecting to a Network

The MTS400 Series System has a 100/10 BASE-T port on the rear panel that allows you to upload and download stream ﬁles.

This section provides instructions for connecting the MTS400 Series System to a single PC or a network and setting the network parameters for the 100/10 BASE-T port.

eries MPEG Player application. This manual also describes the

Connecting the MTS400

Series System to Your

PC(s)

The MTS400 Series System uses the rear-panel 100/10 BASE-T port to communicate with a PC. Use one of the following two methods to connect the instrument to your PC(s).

If you are connecting the instrument directly to a single PC, use a crossover Ethernet cable to connect b etween the 100/10 BASE-T port on the MTS400 Series System and the Ethernet port on the PC. If you need to construct your own crossover cable, Figure 1-1 shows the pin connections to change on a

ight cable to produce a crossover cable.

stra

If you are connecting the instrument to your local Ethernet network, use a

aight Ethernet cable to connect between the 100/10 BASE-T port on the

str MTS400 Series System and the Ethernet hub port of your local network. By connecting to an Ethernet network, you can access the instrument using any PC on the network.

Command Syntax

This section contains information on the Standard Commands for Programmable Instruments (SCPI) and IEEE 488.2 Common Commands you can use to program your MTS400 S following subsections: Syntax, Functional Command Groups, and Remote Commands.

SCPI Commands and Queries

SCPI is a standard created by a consortium that provides guidelines for remote programming of instruments. These guidelines provide a consistent programming environment for instrument control and data transfer. This environment uses deﬁned programming messages, instrument responses, and data format across all SCPI application uses a command language based on the SCPI standard.

instruments, regardless of manufa cturer. The MTS400 Series Player

Creating Commands

The SCP represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes.

Figure 2-1: Example of SCPI subsystem hierarchy tree

You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings.

SCPI commands are created by stringing together the nodes of a subsystem hierarchy and separating each node by a colon.

In Figure 2-1, RECord is the root node and TARGet, TYPE, SIZE, and TIME are lower-level nodes. To create a SCPI command, start with the root node RECord and move down the tree structure adding nodes until you reach the end of a branch. Most commands and some queries have parameters; you must include a value for these p arameters. If you specify a parameter value that is out of range, the parameter will be set to a default value.

I language is based on a hierarchical or tree structure (see Figure 2-1) that

Every parame

The parameter type is listed after the parameter and is enclosed in parentheses, for example, (discrete). Some parameter types are deﬁned speciﬁcally for the MTS400 Series Player application command set and some are deﬁned by ANSI IEEE 488.2-198.

g Commands and

Queries

You can abbrevi short form. This manual shows these short forms as a combination of upper and lower case letters. The upper case letters indicate the accepted short form of a command. You can create a short form by using only the upper case letters. (See Figure 2-2.) The accepted short form and the long form are equivalent and request the same action of the instrument.

Figure 2-2: Example of abbreviating a command

You can chain several commands or queries together into a single message. To create a chained message, ﬁrst create a command or query, add a semicolon (;), and then add more commands or queries and semicolons until you are done. If the comma following ﬁgure illustrates a chained message consisting of several commands and queries. The single chained message should end in a command or query, not a semicolon. Responses to any queries in your message are separated by semicolons.

General Rules

Figure 2-4:

Example of o mitting root and lower-level nodes in a chained message

Here are three general rules for using SCPI commands, queries, and parameters:

You can use single (‘ ’) or double (" ") quotation marks for quoted strings, but you cannot use both types of quotation marks for the same string.

correct: "This string uses quotation marks correctly."

correct: ‘This string als o uses quotation marks correctly.’

incorrect: "This string does not use quotation marks correctly.’

You can use upper case, lower case, or a mixture of both cases for all commands, queries, and parameters.
