The VHFB 8801 from Schwarzbeck Mess-Elektronik is a Balanced Line Impedance Stabilization Network (LISN) that operates from 30 to 300 MHz. It is designed for use during radiated disturbance measurements and is compliant with the CISPR 16-1-4/Ed.5 standard. The LISN serves as a defined RF-termination device at the equipment under test (EUT) mains cable and presents the same impedance to each terminal of the cable. This results in a balanced load and achieves enhanced reproducibility during measurement compared to CMAD equipment. It provides an isolation of more than 40 dB from the auxiliary device to the EUT. 

The VHFB 8801 LISN system is available in an aluminum housing that measures 171 x 105 x 55 mm and has an optional IMA 8803 adapter for impedance measurement.
