The Rohde & Schwarz ESVS30 is a triple-conversion heterodyne EMI test receiver covering 20 MHz to 1 GHz, purpose-built for compliance measurements across CISPR, EN, ETS, FCC, ANSI C63.4, VCCI, VDE, and military standards. Manual operation delivers high frequency resolution with accurate level indication via average and quasi-peak detection. Built-in intelligence reduces measurement time while maintaining outstanding precision, overload immunity, dynamic range, and selectivity.
