Analog/Digital Design and Debug

Analog Digital Design Debug

When you’re innovating to a schedule, there’s no time to track down a logic analyzer or protocol analyzer to find elusive mixed-signal problems. Luckily, new highly-integrated instruments are available and are designed to give you a coherent view into the analog and digital signals, serial protocols, and RF signals that make up today’s complex embedded systems.
