SCPI COMMAND REFERENCE

This chapter contains reference information for programming
the Model 1269 Enhanced Monitoring System (EMS).
Standard Commands For Programmable Instruments (SCPI)
convention rules and syntax are explained in detail. Table 5-1
lists all SCPI commands used for programming the EMS. 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 EMS.
Commands to program the instrument over the VXIbus and
RS-232 interfaces are defined by the SCPI 1994.0 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 chapter, the following conventions
are used for SCPI command syntax.
Square Brackets ( [ ] )
Braces ( { } )
