Device Responses  

Device responses are messages the instrument sends to the controller in reply to a query. 

They may contain measurement results or information on the instrument status.  
The structure and syntax of device messages are described in the following section. 

Structure and Syntax of Device Messages 

Introduction to SCPI 

SCPI (Standard Commands for Programmable Instruments) describes a standard 

command set for programming instruments, irrespective of the type of instrument or 

manufacturer. The objective of the SCPI consortium is to standardize the device-specific 

commands to a large extent. For this purpose, a model was developed that defines 

identical functions of a device or of different devices. Command systems were generated 

that are assigned to these functions and it is possible to address identical functions with 

identical commands. The command systems are of a hierarchical structure. Figure 1-1 

illustrates this tree structure using a section of command system SOURce, which operates 

the signal sources of the devices. The other examples concerning syntax and structure of 

the commands are derived from this command system. 
SCPI is based on standard IEEE 488.2 and uses the same basic syntax elements and 

common commands defined in this standard. Part of the syntax of the device responses is 

defined in greater detail than in standard IEEE 488.2 (see section "Responses to 

Queries"). 

Structure of Commands 

The Commands consist of a header and, in most cases, one or several parameters. The 

header and the parameters are separated by a “white space” (ASCII code 0 to 9, 11 to 32 

decimal, a blank). Headers may consist of several key words. Queries are formed by 

appending a question mark directly to the header. 

Common Commands 

Common (device-independent) commands consist of a header preceded by an asterisk "*" 

and of one or several parameters, if any. 

Examples 

 

*RST 

RESET, resets the instrument 

*ESE 253  EVENT STATUS ENABLE, sets the bits of the event status enable register 
*ESR? 

EVENT STATUS QUERY, queries the contents of the event status register 

Device-Specific Commands 

Hierarchy 

Device-specific commands are of a hierarchical structure (see Figure 1-1). The different 

levels are represented by combined headers. Headers of the highest level (root level) have 

only one key word. This key word denotes a complete command system.
