Conduct measurements to characterize SI performance of active and passive
copper cable products including S-parameters, impedance, eye patterns, and
jitter
Conduct evaluations of measurement data to ensure that program test
requirements are met such as in IEEE, PCI-SIG, and customer specifications
Perform test data de-embedding, discontinuity analysis, and correlations
with connector, PCB, and cable twinax models
Utilize best practices in design, assembly, and calibration of test
equipment setups which include VNAs, TDR/TDT, BERTs and high-speed oscilloscopes
Generation of equipment control and data logging automation scripts for
improved efficiency of test execution and report generation
Design Verification Test (DVT) plans and execution on first article products
including environmental stress margining (4-corners, bend)
Coordinate with appropriate program, engineering, and product line
organizations during test planning, execution, analysis and reporting phases
