Logic Analyzer basics

This page of equipments section of Test and Measurement World covers Logic Analyzer basics. It mentions features of Logic Analyzer from Keysight. The other vendors of logic analyzers are mentioned.

• It is useful to debug and validate activity of multiple buses in automobile system.
• It does analysis of timing between the signals and packet display for critical buses.
• It analyzes memory bus activity.
• It is useful to perform eye scan for digital signal quality analysis.
• It along wth FPGA probe will help to debug FPGA devices.
• Packet decoder portion in logic analyzer will help analyze various automotive network related protocols e.g. CAN, SPI, LIN, FlexRay etc. • Packet generator portion in logic analyzer is used to generate packets or messages on automotive networks with precise control on timings of bits.
