Description
When you are trying to solve a signal integrity problem, the best of all worlds is to have more than one tool to examine the behavior of the system. If there is an Analog-to-Digital Converter (ADC) in the signal path, there are three fundamental issues that can be examined when assessing the circuits performance. All three of these methods evaluate the conversion process, as well its interaction with other portions of the circuit. All data collected for this application note used MXDEV™ hardware and MXLAB software development tools. These three areas of concern encompass the use of frequency analysis (FFTs), time analysis, and DC analysis techniques.
