Measuring Power is not a simple today as it once was. Higher frequency devices, complex loads, challenging test setups, and 2nd order effects all serve to complicate your measurements. Let Picotest help you navigate the waters with tools and techniques designed to increase the fidelity and accuracy of your testing.

The “Measuring Power Application Notebook”, contains over 30 technical articles on power supply test and measurement. The Table of Contents is shown below.

The papers cover a wide range of measurements and test techniques including: Impedance, Stability, Step loading, PSRR, Reverse Transfer, Crosstalk, Noise, PDNs, Wireless Power, Clock Power Optimization, Non-invasive Phase Margin, and Part Parasitics (Resistors, Capacitors, Transformers, MOSFETs)
