11.1 Introduction

This chapter provides an introduction to common instrument interfaces and VLSI testing. Technical details of two matured standards such as the IEEE-488 interface system and the VME bus extension for instrumentation (VXIbus) are given, along with an insight into the evolution of the standards and the future trends.

The IEEE-488 interface system, more commonly known as the general purpose interface bus (GPIB), has been carefully designed to integrate several instruments, together with a computer or a dedicated instrument controller, to simplify the automated measurement process. The bus allows a two-way communication between the controller or the computer with the instruments on the test setup and assists the test engineer in the design and implementation of automatic test equipment (ATE). The particular design philosophy and the interface system allow the necessary flexibility to accommodate different types of electronic instruments manufactured by different manufacturers. The IEEE-488 interface is a digital system, which allows up to 15 instruments or devices to communicate with each other under the control of a master unit or a controller. The devices and instruments are connected together in parallel using specially designed connectors and a cable system referred to as a bus . The supervision of the integrated test setup is provided by the master unit called the controller which is usually a personal computer or a dedicated bus controller. The software needed to control the test setup can be easily written using the popular computer languages. In the past, languages like BASIC...

Products & Services
GPIB Converters
GPIB converters translate data from the GPIB bus to another bus type, and vice versa. For instance, an RS232-to-GPIB converter translates serial commands generated by the RS232 interface into GPIB commands.
Bus Extenders
Bus extenders are used to increase cable lengths for distance-limited bus protocols.
GPIB Controllers and GPIB Interface Boards
GPIB controllers and GPIB interface boards are devices that enable communications between GPIB buses and GPIB networks.
GPIB Products
GPIB products is a general search form for controllers, converters, extenders, expanders, isolators, switches and other products that use the general-purpose interface bus (GPIB). More detailed search forms are available for each type of GPIB product.
CompactPCI and PXI Bus Interfaces
Compact PCI bus interfaces and PXI bus interfaces allow the CompactPCI / PXI system to communicate with other devices or systems.
