이하, 본 발명을 첨부 도면을 참조하여 상세히 설명한다. 도 1 은 본 발명의 디지털 이동통신 기지국 송신 출력 측정장치의 구성을 나타낸 블록도이다. 도 1 에 도시된 바대로, 본 발명의 바람직한 실시예에 따른 디지털 이동통신 기지국 송신 출력 측정장치는, 기지국 송신 출력을 결합하는 방향성 결합기 (20), 상기 기지국 송신 출력을 절대값 측정하는 전력계 (40), 상기 결합된 기지국 송신 출력을 상기 방향성 결합기 (20) 로부터 상기 전력계 (40) 와 기지국 송신 출력 검출기로 배분하는 출력 배분기 (30), 상기 전력계 (40) 와 상기 기지국 송신 출력 검출기를 제어하는 교정장치 제어기 (50) 를 포함한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram showing the configuration of a digital mobile communication base station transmission output measuring apparatus of the present invention. As shown in FIG. 1, a digital mobile communication base station transmission output measuring apparatus according to a preferred embodiment of the present invention includes a directional coupler 20 coupling a base station transmission output, and a power meter 40 measuring absolute values of the base station transmission output. ), An output divider 30 that distributes the combined base station transmit output from the directional coupler 20 to the power meter 40 and the base station transmit output detector, and a calibration to control the power meter 40 and the base station transmit output detector. Device controller 50.

이하, 본 발명의 동작을 첨부된 도 1 을 참조하여 상세히 설명한다. 먼저, 기지국 (10) 이 신호를 송신하면, 이 송신 출력은 방향성 결합기 (Directional Cou -pler, D/C)(20) 로 입력되어 결합된다.Hereinafter, the operation of the present invention will be described in detail with reference to FIG. 1. First, when the base station 10 transmits a signal, this transmission output is input to the directional coupler (D / C) 20 and combined.

그 다음으로, 이 결합된 송신 출력은 출력 배분기 (30) 를 통해 전력계 (40) 와 상기 기지국 (10) 의 기지국 송신 출력 검출기 (12) 로 동시에 입력된다.This combined transmit output is then simultaneously input via power divider 30 to power meter 40 and base station transmit output detector 12 of base station 10.

그런 다음, 상기 전력계 (40) 와 상기 기지국 송신 출력 검출기 (12) 로부터의 출력은 교정장치 제어기 (50) 에 의해 각각 전력이 측정된다.Then, the outputs from the power meter 40 and the base station transmission output detector 12 are respectively measured by the calibration device controller 50.

즉, 상기 교정장치 제어기 (50) 는 상기 전력계 (40) 와 상기 기지국 송신 출력 검출기 (12) 로부터 측정한 값들을 비교하여 그 차(差) (Calibration Data) 를 계산한 다음, 상기 기지국 송신 출력 검출기 (12) 에 저장한다.That is, the calibrator controller 50 compares the values measured from the power meter 40 and the base station transmission output detector 12, calculates the calibration data, and then calculates the base station transmission output detector. Save to (12).

이것을 식으로 표현하면 다음과 같다.If this is expressed as expression, it is as follows.
