Electromagnetic Interference Testing Using Real-Time Scan Measurement
应用文章
Introduction
As the next generation of 5G mobile networks, autonomous driving vehicles, and the Internet of Things (IoT) takes shape, engineers are racing to design more wireless devices to meet accelerating market demand. Simultaneously, the density and complexity of the electromagnetic environment are increasing as a result of the tremendous number of devices that connect wirelessly to the network. These dynamics pose a challenge for electromagnetic compatibility (EMC) testing due to the fact that wireless devices require certification to regulatory compliance standards that are also growing in number.
It is important to identify and isolate EMC issues quickly during EMC compliance testing to help you bring devices to market faster and more efficiently. The Keysight N9048B PXE electromagnetic interference (EMI) test receiver provides a new feature called real-time scan (RTSC) measurement. The new feature significantly improves the diagnostic capabilities of the EMC application and rapidly troubleshoots EMC issues in your device.
This application note will discuss how to use RTSC measurement to perform EMC testing that can detect and evaluate fast transient signal measurements using 350 MHz wide fast Fourier transform (FFT) bandwidth.
