Twin-Coil Siglent Oscilloscope Data and MATLAB Analysis Package

This Zenodo record contains raw Siglent oscilloscope data, oscilloscope screen captures, and MATLAB analysis scripts for a Twin-Coil experimental system. The dataset supports reproducibility of the Twin-Coil testing-environment and frequency-analysis results reported in the associated scientific article. The package includes raw `.DAT` oscilloscope captures for three Twin-Coil measurements, PNG oscilloscope screen captures, and MATLAB scripts for time-domain analysis, Fourier amplitude spectrum analysis up to 40 MHz, dominant-frequency estimation, phase and repeatability evaluation, and Type A uncertainty statistics for coil-to-coil comparison. The experimental system used a UDB120x(S) signal generator, RG-223 50 ohm coaxial connection, MOSFET Switch Board driver stage, Wolfspeed C3M0075120D SiC MOSFET, an L1 coil with 239.47 cm conductor length and 4.375 turns, and an L2 coil with 957.89 cm conductor length and two active 17.5-turn sides. The L1 and L2 resonant sections were tuned for approximately 206--208 kHz, while the coupled operating mode was evaluated around the 171 kHz region. The MATLAB scripts also evaluate high-frequency spectral components in the MHz range.
