The new power rail probe covers power rail transient events up to 4 GHz and offers offset voltage range of ±60V to measure power supplies from plug, down to the pin of an integrated circuit. It also offers a wide dynamic range of ±1V, which, on higher voltage rails, lets you look at droop on the line or when a lot of current is drawn by load or transients. Coupled with the right scope, this powerful combination means you don’t have to worry if the noise you are seeing is from your test equipment or if you’re seeing aggressors in your system that you could never see before.

No matter the industry, power integrity requirements are becoming more and more strict and the number of power rails in a single design is only growing. Depending on your bandwidth needs, Tektronix has a whole suite of oscilloscopes that are optimal to pair with the power rail probe.

For the engineers that are working on the power integrity of fast devices like microprocessors, memory components, FPGAs, storage devices and image sensors, and need the highest accuracy in ripple measurements with transitions in the 2 to 4 GHz range, you have the 6 Series MSO scope that has bandwidths up to 8GHz. When you don’t need as much bandwidth but need to make accurate ripple measurements on an ever-growing number of DC supplies, you can use the up to 8 Channels of the 5 Series MSO. The MDO3000 and MDO400C offer a great option when making traditional ripple measurements under 1GHz at the bench.
