SCPI Command Reference
What’s In This
Chapter
This chapter contains reference information for programming the
Model 3152. Standard Commands For Programmable Instruments
(SCPI) convention rules and syntax are explained in detail. Table
4-1 lists all SCPI commands used for programming the Model
3152. The command summary for each SCPI model is also
included in this chapter.
This chapter teaches you how to use SCPI commands to control
functions, modes, waveforms and other aspects of the instrument.
Prior understanding of SCPI programming is necessary for low
level programming of the Model 3152.
Introduction To
SCPI Language
Commands to program the instrument over the MXI interface bus
are defined by the SCPI 1993.0 standard. The SCPI standard
defines a common language protocol. It goes one step further than
IEEE-STD-488.2 and defines a standard set of commands to
control every programmable aspect of the instrument. It also
defines the format of command parameters and the format of
values returned by the instrument.
SCPI is an ASCII-based instrument command language designed
for test and measurement instruments. SCPI commands are based
on a hierarchical structure known as a tree system. In this system,
associated commands are grouped together under a common
mode or root, thus forming subsystems. Throughout this manual,
the following conventions are used for SCPI command syntax.
Square Brackets ( [ ] )
Enclose optional keywords or
parameters
Braces ( { } )
Enclose parameters within a
command string
Triangle Brackets ( < > )
S u b s t i t u t e a v a l u e f o r t h e
enclosed parameter
Vertical Bar ( | )
Separate multiple parameter
choices
Bold Typeface Letters
Designate factory default values
