This article explains how the inductance of passive probe ground leads can dramatically reduce effective bandwidth, distort measurements, and introduce resonance and frequency-response errors.
This tutorial explains a robust oscilloscope-based method for measuring clock jitter using period statistics, track and histogram analysis, and sample-rate verification techniques.
This article introduces the RP2060 and RP4060 power rail probes, designed for modern 48 V power architectures with high offset capability, low-noise measurements, and high-bandwidth power integrity analysis.
Foundational and advanced concepts for maintaining clean, reliable signals in high-speed designs. Covers measurement techniques, common pitfalls, and practical approaches to identifying and mitigating signal degradation in order to maintain signal integrity and power integrity in electrical designs.
Ground bounce occurs when simultaneous switching currents flow through shared inductance in IC packages, creating voltage noise that can lead to digital bit errors.
Ground bounce occurs when multiple switching signals share a high-inductance return path, creating voltage noise that can disrupt digital I/O performance.
Choosing between a 50 Ω and 1 MΩ oscilloscope input depends on signal bandwidth, cable impedance, and voltage level to ensure accurate and safe measurements.
Characterizing PDN noise—whether from self-aggression, board coupling, or mutual aggressors—is essential to maintaining millivolt-level power integrity margins.
Board pollution noise arises when switching activity and VRM ripple couple onto PCB power planes, and spectral analysis can reveal the dominant aggressors.
