Analog/Digital Design and 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.
This application note provides useful information for verifying and debugging with a Mixed Signal Oscilloscope (MSO) complex designs that may include analog and digital signals and multiple buses.
Find out how the protocol trigger, decode and search capabilities of the popular MSO and DPO Series oscilloscopes solve serial bus integration and debug challenges of many buses such as I2C, SPI , USB, RS-232/422/485/UART, CAN, LIN, FlexRay, Ethernet, and I2S/LJ/RJ/TDM.
This primer explains the basics of Signal Generators, including the many types of generators, their applications and their contribution to a complete test and measurement solution.
