Logic Analyzer Basics

This page describes logic analyzer basics and mention logic analyzer manufacturers. The data present within a complex microprocessor system is continually changing at a fast rate. In order to make meaningful assessment of the state of such a system, it is necessary to analyze the data on instruction basis. This is done using logic analyzer. The technique here is to capture the data over small period of time, store it, analyze it and display as desired.

Logic analyzers are interfaced with the device under investigation by means of an input port and acquisition memory. They are microprocessor controlled. Logic analyzers cost from 500 pound to thousands of pounds based on features/functionalities supported.

Most of the full function logic analyzers allow two modes of display viz. time domain and state domain. The first of these 'time domain' mode involves a form of timing diagram which plots logic waveforms showing the states of each input line over a given interval of time. The display window can usually be scrolled through the acquisition memory so that more detailed analysis is possible.

The alternative 'state domain' mode provides a display in binary/hexadecimal format and may additionally provide for disassembly of data for various microprocessors.
