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.
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.
Ground-referenced passive probes can create dangerous short circuits in high-voltage power systems—use properly rated differential probes instead.
Wide-bandgap power devices demand high bandwidth and superior CMRR, making probe selection critical for accurate high-voltage upper-side measurements.
Power conversion relies on fast-switching MOSFETs and IGBTs that use low-voltage gate-drive signals to control high-voltage, high-current switching efficiently.
In the example to follow, we will show how to use the Teledyne LeCroy 3-phase Power Analysis software or
