dB or not dB?

featured-side
True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field...

Designing for EMI testing (step-by-step guide): Improve your time to market with oscilloscopes

featured-side
Today, R&D engineers face challenging time-to-market goals. Extending the product development schedule and delaying the product launch can prove to be extremely costly in terms of opportunity cost and lost market share. Nearly 50% of products fail EMC compliance the first time. Every day spent on debugging, isolating...

Five techniques for fast, accurate power integrity measurements

featured-side
Rail voltages are getting smaller, and tolerances are decreasing. As a result, making accurate power rail measurements has become much more difficult. Industry dynamics are driving both a decrease in rail voltage values as well as tighter tolerances across a wide range of rails. Making an accurate ripple measurement...
