Automotive radar module and sensor production testing

Maximum automotive radar production yield and performance starts with precise measurements

Increasing demand for automotive radar sensors driven by the large number of radar modules in modern vehicles has led to double-digit growth in radar module production. Accurate and high-performance test equipment enables optimized margins and higher yield in production and this is key as sensor suppliers compete to offer ever-more demanding price-performance points.

Rohde & Schwarz trusted test and measurement solutions are used by almost all leading suppliers of automotive radar modules. Applying leading-edge test technology in production ensures compliance with performance specifications, maximizes yield and helps your competitiveness.
