Computer Model in

Examples

The programming examples provided in this book used an HP 9000 Series 300

technical computer and the HP-BASIC language. However, you can use other

computers and languages with OSA commands and query data over HP-IB.

As an example, you could use an HP Vectra PC compatible computer.Simply

install an HP 82335A HP-IB Interface and Command Library card in the PC

and use a compatible language such as Microsoft QuickC.

Preparing the OSA

When preparing the OSA for programming, you must connect the HP-IB

cables, conrm the HP-IB address, and reset all instruments connected to the

bus.

Typically, you will use the default address setting provided in the introduction

of this book. However, the OSA's HP-IB address can be changed using

front-panel keys or manually by changing SWITCHESnMEMORY on the HP

70950B/1B/2B module. The switches are located on the module cover.

Learning the Basics

Preparing the OSA

To prepare the OSA

1. Connect an HP-IB cable between the computer's HP-IB connector and the

HP-IB connector on the HP 70000 modular measurement system's rear

panel.

HP 70950B/1B/2B OSA modules do not have an HP-IB connector.

Use the connector that is located on the mainframe in which the module

is installed. Be careful not to confuse the display or mainframe's HP-IB

connector with any connectors that may be present on the rear panel of

Preparing the OSA

To change the HP-IB address using switches

The HP-IB address is forced to the switch address setting when the OSA

module SWITCHES/MEMORY selector is set to SWITCHES.

NOTE

The SWITCHES setting must be selected. The MEMORY setting is the factory default setting.
