Abstract
The invention relates to a network analyzer comprising a signal generator for generating an excitation signal which can be supplied to a measuring object connectable to a network analyzer by means of a measuring line, and a measuring bridge which is connected to the measuring line by means of signal transmission. A reference signal corresponding to the excitation signal can be extracted from a reference channel, and a measuring signal corresponding to a signal corresponding to a signal reflected from the measuring object can be extracted from a measuring channel. the measuring bridge comprises a resistive bridge and at least one hybrid coupler which is connected to the resistive bridge in series. the measuring bridge is operated as a resistive bridge in a low frequency range and as a hybrid coupler in a upper frequency range.
