Characterize typical broadband noise in real-time
Switching mode power supply circuit designers can experience failure of the power switches due to increased load on the power supplies. Some reasons for this may be:
- electromagnetic interference in the control electronics,
- local EMI caused by the rapid switching of power switches in switching mode power supplies in other components
- PCB layout itself.
When working with switching mode power supplies, EMxpert allows you to quickly scan a board across a broad frequency range to characterize typical switch mode emissions. This allows the design team to map the noise, confirm its source, and implement appropriate mitigation. The scripting module’s limit line feature also provides a rapid picture of the level of a broad spectrum of noise, so any frequency can be spatially mapped to determine its source.
