Tektronix has introduced its Power Distribution Network (PDN) Analysis Software for 4 Series B, 5 Series B and 6 Series B Mixed Signal Oscilloscopes has been unveiled by Tektronix allowing hardware engineers to integrate power integrity and signal integrity validation in one solution. The PDN Analysis Software was developed to deal with the challenges of contemporary electronic systems such as artificial intelligence servers, supercomputers, and automotive electronics in which power distribution networks need to carry currents that exceed 1,000 amps with extremely strict voltage specifications to avoid errors in data transmission. Unlike conventional validation methods that rely on standalone vector network analyzers and frequency-domain measurements, the new solution leverages real-world step-load testing to assess power rail stability.

Tektronix is the first to integrate the Stability Evaluation for Power Integrity Analysis (SEPIA) methodology, pioneered by Picotest, directly into an oscilloscope, allowing engineers to analyze power supply and voltage regulator performance using realistic load-transient conditions without modifying hardware or disrupting control loops. “The boundary between power integrity and signal integrity has become a primary bottleneck in hardware validation,” said Daryl Ellis, Vice President and General Manager, Signal Acquisition and Analysis Portfolio. “By bringing time-domain stability analysis into the oscilloscope, engineers can evaluate power distribution network behavior under real operating conditions and better understand how power integrity affects signal performance.”
