Some of your favorite instruments have been discontinued, but there's a new generation of products to replace them.
A New Era Awaits
In a move to usher in a new generation of electronic measurement solutions, Keysight has announced the discontinuance of some of its most popular instruments. These products have been replaced by upgraded solutions providing you with better value, while guaranteeing the same quality and performance you've come to rely on.
New, and Very Similar
It’s hard to say goodbye. Especially to trusted workhorses like the 34401A, which has a celebrated history spanning three decades. Keysight has replaced them with modern, upgraded instruments that can provide you not only better value, but greater insight into your measurements. And because the new instruments were crafted by the same team of engineers who originally designed the legacy products, you are guaranteed the same high product quality and confidence. Better yet, they’ve made it easy for you to migrate over to the new products. As your Keysight authorized distributor, we are here to help you — whether it's to make one last purchase of your current equipment or to get a quote on the next generation of test and measurement instruments.
