Using Real-Time Spectral Analysis to Visualize, Measure, and Troubleshoot EMI Signals in a Completely Different Way
By Lee Hill, Founding Partner, SILENT Solutions, LLC
You can’t find or fix what you can’t see! Troubleshooting and localizing intermittent signals or multiple layers of broadband and narrowband signals can be frustrating even for the most seasoned EMC troubleshooter or RF engineer. In this presentation Lee will discuss the capabilities of different types of spectral analysis technologies, and then demonstrate how real-time analysis can literally make previously-hidden signals leap into plain view. His presentation will include live, real-time measurements of realistic intermittent, broadband, narrowband sources such as switching power supplies, PWM motor drives, digital peripherals, as well as Bluetooth and Class D audio amplifiers. Even If you have already heard or read about real-time spectral analysis, this is a great chance to see in person why engineers say “wow, did you see that!” when seeing it for the first time in person.
