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 use of time domain reflectometers for measuring impedance profile and signal integrity on PCBs and cables.
Understanding when to use a TDR, WavePulser 40iX, or VNA depends on bandwidth, rise time, port count, and whether you need time-domain impedance or frequency-domain S-parameters.
