The Effects of Passive Probe Ground Leads
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.
Educational content on design tips and techniques for electrical engineers involved in the design of printed circuit boards, embedded systems, power conversion controls and systems, high-speed serial data links and other electrical and electronic components and systems.
Understanding instantaneous impedance and reflection coefficients explains why transmission line discontinuities distort oscilloscope measurements.
When a low-impedance source drives an unmatched transmission line, alternating reflections can mimic ringing and distort oscilloscope measurements.
Understanding Thevenin source impedance and oscilloscope termination reveals why reflections distort rise time measurements in unmatched transmission line setups.
A simple rise-time experiment reveals why every oscilloscope user must understand transmission line behavior when measuring signals with sub-10 ns edges.
