Overview
The Schwarzbeck VHFB 8801 Balanced VHF-LISN is designed for EMC testing environments where controlled RF termination is required at the equipment under test (EuT) mains cable. It provides a defined and balanced impedance network to ensure accurate and repeatable measurements during radiated disturbance testing.
Operating in the 30 MHz to 300 MHz frequency range, the VHFB 8801 maintains consistent impedance across live and neutral terminals, allowing reliable EMC measurement results. The device complies with CISPR 16-1-4 standards, making it suitable for EMC laboratories, compliance testing facilities, and research environments.
Its compact aluminum housing and laboratory-grade connectors make the VHFB 8801 a practical solution for EMC engineers who require stable and precise LISN performance in high-frequency measurement setups.
