The TimeWise from ETS-Lindgren is an EMC test software designed for flexible data analysis. It allows time domain gating and Fourier analysis of raw data, simulated or collected from equipment like Vector Network Analyzers (VNAs). It consists of a library kit that can be used with other software packages, like MATLAB, C++ and Python, to provide maximum flexibility. In addition, this software features elimination of repeat measurements, enhanced product and compliance troubleshooting, increased accuracy and reduced errors from gated results.
