IntroductionTypes of logic analysersWAVE ANALYSER144Alogic analyseris an electronic instrument that captures and displays multiplesignalsfrom a digital system ordigital circuit.INTRODUCTION

5Presently, there are three distinct categories of logic analysers available in the market:

MODULAR logic analyser

PORTABLE logic analyser

PC BASED logic analyserTYPES OF LOGIC ANALYSER6MODULAR LOGIC ANALYSERMODULARLAS, consist of both a mainframe and logic analyser modules.

The mainframe contains the display, controls, control computer, and multiple slots into which the actual data-capturing hardware is installed.

While LAs modules each have a specific number of channels, and multiple modules may be combined to obtain a very high channel count.

Modular logic analysers are typically more expensive.7PORTABLE LOGIC ANALYSERPortable logic analysers integrate everything into a single package, with options installed at the factory.

While portable logic analysers generally have lower performance than their modular counterparts, they are often used for general purpose debugging by cost conscious users.

8PC BASED LOGIC ANALYSERThe hardware connects to a computer through aUSBorEthernetconnection and relays the captured signals to the software on the computer.

These devices are typically much smaller and less expensive because they make use of a PC's existing keyboard, display and CPU, as compared to portable logic analysers which must provide their own versions of all of that hardware.9

BACK11INTRODUCTIONAn arbitrary waveform generator (AWG) is an advancedsignal generatorthat can generate a waveform of almost any shape.Unlikefunction generators, AWGs can generate any arbitrarily defined wave shape as their output.AWG allows the user to specify a source waveform in a variety of different ways.
