1. Introduction

Users can drive this digital storage oscilloscope by using the GPIB (General

Purpose Interface Bus) system with a computer, or from a computer across the

RS-232 serial connection. Commands sent over either interface can read or set any

oscilloscope’s instructions. This chapter explains how to carry out the following

tasks.

Notes for GPIB installation

If you are setting up the oscilloscope with a GPIB system, please check the

following regulations:

Only a maximum of 15 devices can be connected to a single GPIB bus.

Do not use more than 20 m of cable to connect devices to a bus.

Connect one device for every 2 m of cable used.

Each device on the bus needs a unique device address. No two devices can

share the same device address.

Turn on at least two-thirds of the devices on the GPIB system while you use the

system.

Do not use loop or parallel structure for the topology of GPIB system.
