Abstract
본 발명은 위성 발송 수신을 위한 안테나와 LNB(Low Noise Blockdown Converter) 설치시 LNB 출력의 세기를 측정하여 위성과 안테나 방향을 일치시키기 위한 LNB 출력 세기 표시 장치에 관한 것으로, 안테나로부터 수신되는 고주파 신호를 저주파 신호로 변환하는 LNB 회로부(201)과, 상기 LNB 회로부(201)에서 출력되는 RF 신호를 검파하고 상기 LNB회로부 (21)에 전원을 공급하는 튜너부(202), 상기 LNB회로부 (201)에서 출력되는 RF 신호를 튜너부(202)로 전송하고 튜너부(202)로부터 제공되는 전원을 LNB회로부 (201)에 제공되는 동축 케이블(203)을 구비한 위성 방송 수신 장치에 있어서; 상기 동축 케이블(203)으로부터 전원을 인가받아 상기 RF신호에 대한 C/N 비를 검출하여 이를 전압으로 변환하는 C/N비 검출부(204), 상기 동축 케이블(203)로부터 전원을 인가받아 C/N비에 상응하는 신호 레벨을 표시하는 표시부(205), 상기 C/N비 검출부(204)와 상기표시부(205)에 상기 동축 케이블(203)의 전원이 공급되도록 상기 동축 케이블 (203)상의 RF 신호가 상기 C/N비 검출부(204)에 입력될수 있도록 상기 C/N비 검출부(204) 및 표시부(205)와 상기 동축 케이블(203)을 접속시키는 컨넥터(206)로 구성한다.The present invention relates to an LNB output strength display device for measuring the strength of the LNB output when the LNB (Low Noise Blockdown Converter) and LNB (Low Noise Blockdown Converter) are installed to match the satellite and antenna directions. In the LNB circuit unit 201 for converting the low frequency signal, the tuner unit 202 for detecting the RF signal output from the LNB circuit unit 201 and supplying power to the LNB circuit unit 21, the LNB circuit unit 201 A satellite broadcast receiving apparatus having a coaxial cable 203 which transmits an output RF signal to a tuner unit 202 and provides a power supply from the tuner unit 202 to the LNB circuit unit 201; The C / N ratio detector 204 receives power from the coaxial cable 203 and detects the C / N ratio of the RF signal and converts the C / N ratio into a voltage, and receives power from the coaxial cable 203. RF on the coaxial cable 203 so that the power of the coaxial cable 203 is supplied to the display unit 205, the C / N ratio detector 204, and the display unit 205, which display a signal level corresponding to the N ratio. The C / N ratio detection unit 204 and the display unit 205 and the coaxial cable 203 are connected to each other so that a signal can be input to the C / N ratio detection unit 204.
