SCPI Commands and Queries
3026 Programmer Manual
This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common Commands you can use to
program your 3026 Realtime Spectrum Analyzer. The information is organized
in the following subsections:
H SCPI Commands and Queries – This subsection describes the SCPI
command organization and syntax
H IEEE 488.2 Common Commands – This subsection lists the commands and
argument structures that are common to all SCPI commands
SCPI is a standard created by a consortium that provides guidelines for remote
programming of instruments. These guidelines provide a consistent program-
ming environment for instrument control and data transfer. This environment
uses defined programming messages, instrument responses, and data format
across all SCPI instruments, regardless of manufacturer. The realtime spectrum
analyzer uses a command language based on the SCPI standard.
The SCPI language is based on a hierarchical or tree structure (see Figure 2-1)
that represents a subsystem. 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.
