An 8-Channel Logic Analyzer is a compact yet powerful tool designed for capturing, analyzing, and debugging digital signals in embedded systems, IoT devices, and microcontroller-based projects. It allows researchers and developers to monitor up to 8 digital channels simultaneously, making it ideal for studying communication protocols, timing relationships, and system behavior in real time.
By interfacing with a PC via USB and using dedicated software, the logic analyzer provides high-resolution timing analysis, protocol decoding (such as I²C, SPI, UART, 1-Wire, CAN, etc.), and waveform visualization—critical for debugging complex digital systems.
