Tektronix 5-PWR Advanced Power Measurement and Analysis

Overview

Tektronix 5-PWR is an advanced power measurement and analysis software package designed for 4/5/6 Series MSO oscilloscopes. It combines high-precision analog-to-digital converters with automated power analysis tools and a comprehensive suite of voltage and current probes, including state-of-the-art IsoVu optically isolated voltage probes. This enables engineers to perform accurate power system measurements and optimization without requiring deep expertise in power conversion.
