Abstract: An integrated spectrum analyzer is provided to enable the spectrum analyzer to measure both magnitude and phase of a radio signal by using an embedded oriented coupler. A directional coupler(110) outputs an output signal via an output port and a coupled signal via a couple ports. A receiver(120) varies signal ranges of the output signals of the directional coupler and outputs the result via corresponding output ports. A first switch(130) selectively transfers the signal from each of the output ports of the receiver. A second switch(140) is installed between the couple port of the directional coupler and the input port of the receiver. The second switch selectively transfers the coupling signal from the couple port to the receiver under a control signal. A reference signal processor(150) temporarily stores magnitude and phase components of a source from the receiver and stores a reference signal under the control of the external control signal. A signal processor(160) temporarily stores magnitude and phase components of the source from the receiver and processes the signal so that a response characteristic graph is to be used for respective frequencies. A controller(170) controls the first and second switches and calculates the magnitude and phase of the source stored in the reference signal processor to set the result as the reference signal. The controller mixes the signals stored in the signal processor, compares the mixed signal with the reference signal, and outputs the compared result to the signal processor. A control panel(180) and a display(190) are further included.
