• Set with 2 baluns for tests according to IEC / EN 61000-4-19, Fig. 4
• Conversion of unbalanced 50 Ω input/output impedance to balanced 10 Ω
• To check the decoupling attenuation of the CN 19-U

To check the decoupling attenuation between the main and EUT ports of the CN 19-U, two impedance transformers are required to convert the unbalanced 50 Ω input and output impedance of the network analyzer to a balanced 10 Ω.
