Getting Started with SCPI

Details of Commands and Responses

This section describes the syntax of SCPI commands and responses. It provides many

examples of the data types used for command parameters and response data.

Program Message Syntax

These program messages contain commands combined with appropriate punctuation and

program message terminators.

Figure 1-12. Simplified Program Message Syntax

You can send common commands and subsystem commands in the same message as shown

in Figure 1-12. If you send more than one command in the same message, you must

separate them with a semicolon. You must always end a program message with one of the

three program message terminators shown in Figure 1-12. Use <new line>, <END>, or

<new line> <END> as the program message terminator. The word <END> means that EOI

is asserted on the GPIB interface at the same time the preceding data byte is sent. Most

programming languages send these terminators automatically. For example, if you use the

HP BASIC OUTPUT statement, <new line> is automatically sent after your last data byte.

If you are using a PC, you can usually configure the system to send whatever terminator

you specify.
