Abstract
The bridge circuit receives the balance signal output from the balanced signal source, which generates a broad-band balanced signal over a frequency band of a direct current to several tens of MHz as a reflection-characteristic measuring bridge. The balance signal source is constructed by connecting in series the first balance output type circuit whose equivalent circuit is represented by the parallel-connection circuit of the resistor R.sub.1 and the electrostatic capacitor C, and the second balance output type circuit whose equivalent circuit is represented by the parallel-connection circuit of the resistor R.sub.2 and the inductance L, R.sub.1, R.sub.2, C and L of the first and second balanced output type circuits are set to such values that the output impedance of the balanced signal source is regarded as a pure resistance so that the balanced signal can be stably generated over the broad frequency band without suffering affection of the electrostatic capacitance of the first balanced output type circuit and the inductance of the second balanced output type circuit.
