Balanced Impedance Adaptor To facilitate high-accuracy impedance measurements, inputs to Impedance Analyzers and LCR Meters are configured as four-terminal Kelvin connections – two pairs of current and potential terminals. These are usually unbalanced, i.e. one side grounded. To measure balanced impedances requires a balanced to unbalanced converter, usually a balun transformer. The NH16552 includes a balun transformer and features four terminals on the unbalanced side to conveniently interface with the measuring...
