Troubleshooting Distributed Power Systems: Measuring Ripple (Part 7 of the ongoing series)


Measuring Ripple - J2130A DC Bias Injector serves as a DC Blocker.

And by taking measurements across all three test domains, designers can trace power supply ripple-related problems back to root causes such as switching frequency, load dynamics, and PCB crosstalk as explained here. Various test setups, which include instruments from Picotest and other vendors, and measurement techniques are described in this video and results of example ripple measurements using different point of load regulators (POLs) are discussed. Along the way, Sandler gives test tips to help engineers avoid common measurement pitfalls.
