(Keysight Technologies: Santa Rosa, CA) -- Keysight Technologies Inc. has introduced the industry’s highest bandwidth and lowest noise oscilloscope probe for making power integrity measurements to characterize DC power rails.

The new Keysight N7020A power-rail probe specifications are tailored for a wide variety of DC power-rail measurements. Probe specifications include very low noise, a large ±24-V offset range and 2-GHz bandwidth.

Across the electronics industry, engineers are designing successive generations of products with decreasing DC operating voltages as a way to reduce power and increase clock and data speeds. As DC power rails have shrunk in size, so have the tolerance on those power rails. One of the biggest sources of clock and data jitter in a digital system is noise on the DC power supplies. Development teams in almost all electronic industries measure the integrity of DC power rails and need tools that provide the signal detail associated with smaller and smaller DC voltages—often just a few millivolts.
