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.

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.
These nine practical DDR probing tips help reduce strain, improve signal integrity, and avoid common measurement pitfalls when working with high-speed DRAM interfaces.
