Advantages of Logic Analyzer | disadvantages of Logic Analyzer

This page covers advantages and disadvantages of Logic Analyzer. It mentions Logic Analyzer advantages or benefits and Logic Analyzer disadvantages or drawbacks.

Introduction:
Logic analyzer is used for multiple channel or signal measurements simultaneously. It captures the signals and displays them simultaneously on the screen from digital system/circuit. It possesses advanced triggering features and hence it is handy tool for measuring timing relationships between signals in digital system. It requires hardware and software in order to perform measurements as shown in the figure-1.

Logic Analyzer

It uses dedicated dedicated bus and protocol analysis functionality. This helps logic analyzers to perform analysis on different bus protocols such as UART, SPI, I2C, SSI etc. It uses USB 2.0 high speed interface with PnP (Plug and Play) support.

Benefits or advantages of Logic Analyzer

Following are the benefits or advantages of Logic Analyzer:
➨It supports measurements of multiple channels commonly not supported by oscilloscope. This is very useful in debugging microprocessor or microcontroller based boards. Normally logic analyzer supports 16 or more channels. Advanced logic analyzers even support 300 channels.
➨High performance
➨Lower costs
➨Easy to carry
➨Convenient to use
➨Extendibility

Drawbacks or disadvantages of Logic Analyzer

Following are the disadvantages of Logic Analyzer:
➨It does not focus on analog characteristics of the signal and their specific values. Hence it is not suited for such analog measurements unlike oscilloscope. Logic analyzer is used for digital measurements.
