Impact of Short-Time Fourier Transform Parameters on the Accuracy of EMI Spectra Estimates in the 2-150 kHz Supraharmonic Interval: Datasets and Supplementary Materials

The dataset contains measurements of conducted emissions of two ITE SMPSs named "Black" and "Ktec" (26.4 W and 18 W, respectively) at two different operating conditions (25% and 90% of the load condition). The measurements were carried out with an 8-bits digital oscilloscope in the time domain with a sampling frequency of 10 MSa/s and consist of time records of 2 M samples. A Matlab script is also provided in order to load the data into the Matlab workspace. The script plots also the measured voltage versus time.本数据集包含两款分别命名为"Black"与"Ktec"的信息技术设备（Information Technology Equipment, ITE）开关电源（Switching Mode Power Supply, SMPS）的传导发射（conducted emissions）测量数据，二者额定功率分别为26.4 W与18 W，测试覆盖两种不同负载工况：负载率25%与90%。本次测量采用8位数字示波器在时域下完成，采样频率为10兆采样每秒（10 MSa/s），每条时域记录包含200万采样样本（2 M samples）。此外还附带了Matlab脚本，可将数据导入Matlab工作区，并绘制测量电压随时间变化的曲线。
