RFLogic Analyzer Basics and Manufacturers

This page describes logic analyzer basics and lists some prominent logic analyzer manufacturers.
In complex microprocessor systems, data changes rapidly and constantly. To meaningfully assess the system’s state, it’s crucial to analyze the data on an instruction-by-instruction basis. This is where logic analyzers come in. The fundamental technique involves capturing data over a short period, storing it, analyzing it, and displaying it in a desired format.
Logic analyzers interface with the device under investigation via an input port and acquisition memory. They are typically microprocessor controlled.
Logic analyzer prices range from approximately 500 pounds to several thousand pounds, depending on the features and functionalities supported. Most full-function logic analyzers offer two display modes: time domain and state domain.
The ‘time domain’ mode displays a timing diagram plotting logic waveforms, showing the states of each input line over a given time interval. The display window is usually scrollable, allowing for more detailed analysis of the captured data.
The alternative ‘state domain’ mode presents data in binary or hexadecimal format and often includes data disassembly capabilities for various microprocessors.
