Multi-Clock Comb Generator Finds PDN Sensitivities and EMI
Picotest has recently announced their USB multi-clock comb generator, the J2150A, designed to ferret out resonant sensitivities in your power delivery network (PDN). The J2150A is a troubleshooting tool to help reveal resonances in power bus and power supply circuitry. It’s also very useful as an EMC/EMI troubleshooting tool and can also help identify EMI resonances that may … [Read more...]
Nanoscale Materials for the Internet of Things
Recently the Harvard SEAS official website said that the Internet of Things (IOT) may generate more than $14 trillion in economic activity by 2025, but many in the industry believe that significant policy changes will be required to enable the needed connections of assorted devices while avoiding interference if this is to be the case. Researchers at the Harvard John A. … [Read more...]
