Logic Analyzer

A logic analyzer is a digital test instrument that captures, displays, and analyzes multiple digital signals simultaneously over time. It connects to digital circuits via multiple input channels (typically 8, 16, 32, or more) to monitor logic states (high/low) and timing relationships between signals. Logic analyzers are essential for debugging digital systems, verifying protocol communications, and analyzing complex timing issues in microprocessors, FPGAs, and other digital hardware. Unlike oscilloscopes that show analog waveforms, logic analyzers focus specifically on digital signal patterns and can decode various communication protocols like SPI, I2C, and UART.
