GPIB Reference
Introduction
This chapter provides reference information for the gpib commands used to control the 4349B
in the gpib remote mode .

The 4349B can be operated using the General Purpose Interface Bus(gpib ). GPIB commands
correspond to the Standard Commands for Programmable Instruments(scpi ). SCPI is the
instrument command language for controlling instrument that goes beyond IEEE 488.2 to
address a wide variety of instrument functions in a standard manner .
GPIB Commands
GPIB commands can be separated into two groups: common commands and subsystem
commands .
Common Commands
Common commands are generally not measurement related, but are used to manage macros ,
status registers , synchronization, and data storage . All common commands begin with an
asterisk. Common commands are dened in the IEEE 488.2 standard.
Common Commands
*CLS
*ESE <numeric value>
*ESE?
*ESR?
*IDN?
*LRN?
*OPC
*OPC?
*OPT?
*RCL <numeric value>
*RST
*SA V <numeric value>
*SRE <numeric value>
*SRE?
*STB?
*TRG
*TST?
*W AI
Subsystem Commands
Subsystem commands include all measurement functions and some general purpose functions .
Each subsystem is a set of commands that roughly corresponds to a functional block inside the
instrument. F or example , the SOURce subsystem contains commands for signal generation,
while the ST A Tus subsystem contains commands for accessing status registers .
Subsystem commands have a hierarchical structure , called a command tree, which consists of
several key words separated by a colon between each word.
