Working familiarity with high-speed test and measurement equipment such as oscilloscopes, BERTs, VNAs, TDR, jitter analyzers, logic analyzers, power supplies, electronic loads, and compliance test kits - comfortable operating, configuring, and troubleshooting these instruments, with the ability to deepen expertise on specific tools as needed. Maintain dedicated RMA test setups used to examine field-returned chips - keep the systems, test programs, and instrumentation always ready to receive and process RMA units the moment they arrive, including ensuring proper test-hole-plug coverage and re-test readiness whenever needed.
