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.
Everything power. From watts to megawatts, millivolts to kilovolts, milliamps to kiloamps, single-phase to three-phase. From power semiconductor devices (MOSFETs and IGBTs) to inverter subsection to complete power conversion systems. From PDNs and power integrity in an embedded system to utility T&D applications and everything in between.
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.
Attaching multiple probes to the same test point can cause probe loading and interference, leading to inaccurate oscilloscope measurements and distorted waveforms.
Electrical power spans generation, distribution, and consumption—where motors and modern power electronics dominate global energy use and measurement challenges.
AC line power is a rotating voltage vector measured in RMS terms, with peak, peak-to-peak, and rectified values that differ significantly from the familiar “120 VAC” rating.
Three-phase AC voltages consist of three balanced sinusoidal vectors separated by 120°, with measurable differences between line-to-line and line-to-neutral values.
AC line current is a rotating sinusoidal vector—single- or three-phase—whose accurate measurement depends on system configuration and the right choice of current sensor.
Three-phase power is calculated by summing individual phase values, with special considerations for line-to-line measurements, delta windings, and two-wattmeter methods.
