RADIO NETWORK MANAGEMENT APPARATUS A SIGNAL GENERATOR AND SPECTRUM ANALYZER AND THE FUNCTION MESUREMENT METHOD THEREOF

摘要

The present invention is also to measure the isolation more easily without the need for expensive measuring equipment for isolation prior between the transmitting and receiving antenna must be determined if the operation to install the radio relay device as well as isolation, as well as an antenna, and cable It relates to the VSWR measurement, DTF measurement function measurement method using a radio network management device having a signal generator and a signal analyzer to the electric field intensity measured in the selective and him.; The present invention to achieve this, analysis of the reference signal and the transmitted signal is reflected by the external generated from the signal generator and the signal generator for generating a reference signal by the frequency-generating unit to have the desired amplitude and phase in the frequency band to be measured signal analyzer there is interconnected by a voltage standing wave ratio combining unit, wherein the voltage standing wave ratio combining unit, a directional to being applied to the reference signal generated by the signal generator separating the reference signal to be transmitted on the forward path and reverse path a combiner, the control portion of the separation by the directional coupler standard signal as soon transmitted using the forward path as well as one or more high-frequency switch for setting the transmission path so that the portion of the reference signal transmitted using a reverse path by switching control It is done by receiving a high-frequency switch matrix Providing the radio network management device having a signal generator and a signal analyzer and a method is provided to be used as the isolated him as measured VSWR, DTF, electric field strength and the like.
