A return loss bridge circuit for testing a balanced test impedance includes an input connector and a reflection connector. The input connector and the reflection connector are electrically connected to an output of a network analyzer and an input of the network analyzer, respectively. The return loss bridge circuit further includes a reference impedance connected between the input and reflection connectors, first and second transformers and a common mode choke. The common mode choke is electrically connectable to the balanced test impedance.
