Rohde & Schwarz ESHS10

R&S ESHS10 EMI Test Receivers, 10: 9 kHz to 30 MHz

The receivers ESHS 10 is suitables for measuring electromagnetic interference in line with commercial standards:
• CISPR16, VDE0876 and ANSI C63.2
• EN55011 to 55022, ETS, FCC, VCCI and VDE 0871 to 0879 and ANSI C63.4

The instruments are ideal for routine tasks in industry such as development and approval tests in line with commercial standards. Featuring mains-independent battery powering, they are also suitable for mobile applications at EMC service providers, test houses and safety standard authorities.
