Rohde & Schwarz ESHS10 9KHz-30MHz EMI Test Receiver

The Rohde & Schwarz ESHS10 is a dedicated EMI test receiver for electromagnetic interference compliance verification across 9 kHz to 30 MHz. It delivers precise measurement capabilities essential for validating radiated and conducted emissions against regulatory standards including CISPR, FCC, and VDE. The instrument combines a tracking generator for filter characterization with selectable detector modes - peak, quasi-peak, and average - to satisfy international EMI measurement requirements in laboratory settings demanding high accuracy and repeatability.
