In this video, we are performing a non-invasive stability measurement (NISM) on our PDN to check impedance. This specific stability measurement allows us to evaluate the health of the power delivery network without accessing with the feedback loop. When looking at the measurement graph in the Bode Analyzer Suite, we can see that there is a sharp peak in the graph, indicating PDN instability. We are measuring the output of the voltage regulator module (VRM) and using the Bode Analyzer Suite to...

While prototyping a design, it is incredibly helpful to have an in-house EMC pre-compliance testing setup to troubleshoot your product. Having this capacity can save you from having to send your design into a third-party lab for multiple rounds of compliance tests, speeding your design cycle and saving costs in the long run. Investing in your own EMC test setup may seem like a daunting prospect, but you don’t need to spend tens or hundreds of thousands of dollars on an anechoic chamber and...

Diagram of sample Signal Edge Solutions mobile lab setup In an increasingly RF connected world, EMC compliance testing is necessary to ensure products are robust enough to operate in a safe and reliable manner in consumer and commercial environments. Nearly every country has EMC regulations and standards that electronic devices or machines on the market must be compliant with for their intended use. Products that fail to meet electromagnetic compatibility (EMC) compliance can cause...
