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

GPIB Commands

Status Reporting Structure
Trigger System
Data Transfer Format
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 de ned in the IEEE 488.2 standard.

*ESE numeric value
*ESE?
*ESR?
*IDN?
*LRN?

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. For example, the SOURce subsystem contains commands for signal generation,
while the STATus 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.
