The Rohde & Schwarz ESIB40 is a high-performance EMI test receiver and spectrum analyzer engineered for electromagnetic compatibility (EMC) testing across CISPR, EN, VDE, ANSI, FCC, BS, ETS, VCCI, MIL-STD, VG, and DEF-STAN standards. Compliant with CISPR 16-1-1, it combines receiver sensitivity with spectrum analyzer flexibility for product development from functional measurements through final certification.
