CISPR and ANSC C63 Overview on Site Validation Measurements from 18 GHz to 40 GHz

Join us at Nemko for an exciting presentation and LIVE DEMO on a novel approach for EMC chamber validation beyond 18 GHz, currently under consideration in ANSC C63 and CISPR standards. By integrating Cylindrical Mode Filtered Site Voltage Standing Wave Ratio (CMF SVSWR) with Compressed Sensing (CS), we address inherent challenges in traditional SVSWR methods, such as inconsistency and slow data acquisition. CMF SVSWR utilizes circular path measurements and mode domain post-processing to discern antenna and chamber reflections, crucial for comprehensive VSWR analysis. Compressed Sensing, a data-driven machine learning technique, exploits signal sparsity to reconstruct data from fewer randomly sampled measurement points, thereby reducing test times and eliminating the need for precise turntable positioning. During the demo in the semi-anechoic chamber at Nemko, attendees will see how CMF SVSWR provides a more comprehensive evaluation of the EMC chamber quiet zone and can be readily measured without any special positioning fixtures. The demonstration will show an entire measurement process including the post processing which can be performed in real time. This meeting is open to all and there is no charge to attend, but advance registration is required! Thank you to host Nemko for providing the chamber access and complimentary dinner.
