Command Syntax

SCPI Commands and Queries

2-2
The waveform generator uses a command language based on the SCPI standard.
The SCPI (Standard Commands for Programmable Instruments) standard was
created by a consortium to provide guidelines for remote programming of
instruments. These guidelines provide a consistent programming environment for
instrument control and data transfer. This environment uses defined program-
ming messages, instrument responses and data formats that operate across all
SCPI instruments, regardless of manufacturer.
The SCPI language is based on a hierarchical or tree structure that represents a
subsystem (see Figure 2–1). The top level of the tree is the root node; it is
followed by one or more lower-level nodes.

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.
