Rohde & Schwarz ESIB7 EMI Test Receiver

The Rohde & Schwarz ESIB7 is an EMI test receiver engineered for electromagnetic compatibility (EMC) compliance testing across civilian and military regulations. It combines high sensitivity, extensive dynamic range, and precise selectivity with the operational flexibility of a spectrum analyzer. The instrument meets CISPR 16-1-1 and supports measurements per CISPR, EN, VDE, ANSI, FCC, BS, ETS, VCCI, MIL-STD, VG, DEF-STAN, DO160, and GAM EG13 standards.
