Transmission line losses—driven by skin effect and dielectric properties—play a critical role in degrading high-speed signal integrity and eye performance.
Transmission line loss directly affects eye diagram quality, with around −12 dB at Nyquist marking the limit before signal integrity rapidly degrades without equalization.
Insights into performing EMC, ESD, and EMI compliance tests in lab settings and pre-compliance diagnosis and mitigation using time- and frequency-domain measurements. Focuses on practical test methods to make measurements, identify noise sources and improve electromagnetic compatibility.
Accurate ESD pulse measurement depends on using a high enough sampling rate to capture sufficient points on the rising edge for reliable characterization.
Accurate EMC/ESD testing begins with verifying surge and ESD pulse characteristics—such as rise time and bandwidth—using high-speed oscilloscopes before applying them to the DUT.
A real-time oscilloscope can help engineers identify EMI sources and reduce radiated emissions before submitting products for costly FCC compliance testing.
