6.3 SCPI Command Structure and Syntax
SCPI describes a standard command set for programming instruments, irrespective of
the type of instrument or manufacturer. The goal of the SCPI consortium is to standard-
ize the device-specific commands to a large extent. For this purpose, a model was
developed which defines the same functions inside a device or for different devices.
Command systems were generated which are assigned to these functions. Thus it is
possible to address the same functions with identical commands. The command sys-
tems are of a hierarchical structure.
SCPI is based on standard IEEE 488.2, i.e. it uses the same syntactic basic elements
as well as the common commands defined in this standard. Part of the syntax of the
device responses is defined with greater restrictions than in standard IEEE 488.2 (see

6.3.1 Structure of a Command
The commands consist of a so-called header and, in most cases, one or more parame-
ters. Header and parameter are separated by a "white space" (ASCII code 0 to 9, 11 to
32 decimal, e.g. blank). The headers may consist of several key words. Queries are
formed by directly appending a question mark to the header.

Common commands consist of a header preceded by an asterisk "*" and one or sev-
