Scope Embedded Power Integrity Analysis: PDN Analysis on 4, 5 and 6 Series B MSOs
2026-09-22
Watch this demonstration of Scope Embedded Power Integrity Analysis (SEPIA) and learn how it compares with traditional methods for evaluating the stability of a voltage regulator and power distribution network (PDN). The demonstration uses Power Distribution Network Analysis software running on a 6 Series B MSO oscilloscope, with a programmable voltage regulator serving as the device under test.
The video provides a brief introduction to SEPIA and highlights some of the limitations of using Bode plots to evaluate stability. It then presents a detailed explanation of the test setup, including the oscilloscope, function generator, and Picotest load stepper. The voltage probing system combines a Tektronix power rail probe with a Picotest common-mode isolator and browser probe.
The video also includes a brief overview of Option 6-PDN Power Distribution Network Analysis software, which includes SEPIA as one of its capabilities.
