How your use of power sensors and spectrum analysers can influence outcomes in RF and microwave power measurements, writes Giovanni D’Amore of Keysight Technologies. The ability to make consistent ...

A power supply rejection ratio test set-up can be configured with key components, explains Andreas Ibl and Marcus Sonst. The power supply rejection ratio (PSRR) indicates the stability of a power ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

The prosaic DC power supply is receiving scrutiny as supply voltages continue to get smaller. Supply tolerances are getting tighter as users try to decrease power, increase yield and minimize supply ...

This product is featured in EDN's Hot 100 products of 2015. See all 100 here. When designing power supplies, power converters, inverters, and other devices that connect to the power grid, you often ...

Digital or vector modulation can provide increased spectral efficiency, higher data security, and higher quality communications. This comes at a cost of increased system complexity and a resultant ...

We won’t mention names, but we are always dismayed to see people twist knobs randomly on a scope until it shows a good picture. These days, there’s the dreaded auto button, too, which is nearly as bad ...
