Why it's trending
When microcontroller communication fails, a logic analyzer shows exactly what happened on the wires.
USB 3.0 analyzers
Fast USB transfers allow long captures at high sample rates.
Protocol decoding
Analyzers decode I2C, SPI, UART, CAN and more automatically.
Scope + analyzer
Use a scope for signal quality and an analyzer for logic.
