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.

Power conversion relies on fast-switching MOSFETs and IGBTs that use low-voltage gate-drive signals to control high-voltage, high-current switching efficiently.
While built-in isolated inputs offer convenience and safety, high-quality isolated probes deliver superior noise immunity and performance in fast-switching, high-voltage environments.
A simple in-circuit test reveals how a differential probe’s CMRR behaves across frequencies and how closely it matches published specifications in real measurement environments.
