OFC 2025: Test equipment
This year’s OFC in San Francisco featured one thing, or so it seemed: 1.6T. Every company making optical modules was showing them lest they be left behind in the always accelerating data rate race. As with any emerging technology, test equipment must lead the way. After all, how do you know if anything works unless […]
Characterize EMI from dc-dc converter ringing
Switching power supplies produce radiated and conducted emissions caused by ringing. Oscilloscope and spectrum-analyzer measurements let you see them. DC-DC converters are ubiquitous in most electronic products. While more efficient than linear regulators, they can also produce considerable amounts of interference that can affect nearby circuits. The measurements in this article show how ringing occurs […]
