Understand RF emissions at the hardware level.
Switching activity can couple noise onto power and ground and produce radiated emissions. CC-100 circuitry targets that energy. Explore emissions reduction as a measurable engineering objective for your system.
What the device connects to
PowerStic and PowerStic-AI connect to USB power and ground, with no connection to the USB data lines. The circuitry acts on coupled electrical noise rather than reading or filtering USB data.
Lower emissions may be relevant to an electromagnetic side-channel evaluation. The useful question is whether the measured change affects the specific signal and threat being assessed.
Define what the test must show
Emissions. Compare the relevant frequency range at consistent measurement points.
System conditions. Hold workload, equipment, and operating state comparable.
Security outcome. Assess the specified threat model separately from power savings or a lower noise reading.
Choose an evaluation around your objective.
For an existing system, discuss a USB-device trial. For a chip design, review CC-100IP-RF. Define the target frequencies and threat model before purchasing; validate any security outcome separately from energy savings.
