SWR 과 EU1KY 장비 소개 ( 1 )

안녕하십니까 ? 아마츄어 무선을 함에 있어 각 종 악세사리에 대한 설명서가 부족하여  방장님께 부탁을 하여 이방을 개설 하였습니다. 어려운 물리학과 전자공학을 배제한 가장 쉬운 용어로 설명을 하고자 합니다만 ?????  여러가지 의문점은 언제든지,  리플 주시기 바랍니다. @@ 사진 및 제품은 저와 무관하며, 가능한  출처를 표시 히였으며, 인터넷 웹 서핑 자료임을 밝혀 둡니다..@@  ======================= SWR 이란 ? 아마츄어 무선 취미를 함에 있어 가장 필요한 측정 장비가 무전기, 안테나, SWR 메타 3가지 정도 라고 생각 합니다. SWR 은 Standing Wave Raio ( 정 재파비 ) 의 약자로 무전기와 안태나 사이의 정합 정도를 측정하는 장비 입니다. 무전기의 출력이 안태나와 의 정합(매칭) 정도를 수치로 나타낸 장비이며,  여러 나라 회사의 디양한 장비가 있으나, 가까운 일본의 다이야 몬드 사 제품인 SX-100, 200,400, 600 의 제품들이 많이 소개 되어 있고 사용을 하는 중입니다... 이 장비는 SWR/출력 수치만을 나타내므로 안태나 자체의 임피던스나, 동축케이블 길이 등은 측정이 어렵습니다. <img src="https://t1.daumcdn.net/cfile/cafe/99E449465CFE576904" class="txc-image" width="284" style="clear: none; float: none;" border="0" vspace="1" hspace="1" data-filename="imagesSX600.jpg" exif="{}" actualwidth="284" id="A_99E449465CFE576904D1D0"/>( 출처 :  인터넷 웹 서핑: <a href="http://www.gogle.com">www.gogle.com</a> ) 그래서 많이 사용하는 장비가 미국의 MFJ 회사 제품의  MFJ-259/B 장비 입니다.   이 장비는 주파수, SWR. 케이블 길이, 임피던스 등 을 측정하여 눈금으로 표시 하였습니다. 하지만, <img src="https://t1.daumcdn.net/cfile/cafe/99E7A8495CFE582403" class="txc-image" width="480" style="clear: none; float: none;" border="0" vspace="1" hspace="1" data-filename="259.jpg" exif="{}" actualwidth="480" id="A_99E7A8495CFE58240395F4"/>( 출처 :  인터넷 웹 서핑: <a href="http://www.gogle.com/">www.gogle.com</a> ) 시대의 변화에 따라 지금까지의 아나로그 장비의 지침 에서 벗어나, 모든 현상을 눈으로 바로 보고자 하는 염원의 결과. 디지탈 화 된 각 종 부품의 발달과 S/W 개발을 통하여 VNA ( Vector Network Analyzer )급  장비가 출시 됩니다. <img src="https://t1.daumcdn.net/cfile/cafe/99C02B4F5CFE58AF1E" class="txc-image" width="549" height="354" style="width: 549px; height: 354px; clear: none; float: none;" border="0" vspace="1" hspace="1" data-filename="SiglentSVA_1500x871.jpg" exif="{}" actualwidth="1024" id="A_99C02B4F5CFE58AF1EE6A0"/> 출처 : <a href="https://m.eet.com/media/1305413/SiglentSVA_1500x871.jpg">https://m.eet.com/media/1305413/SiglentSVA_1500x871.jpg</a> 스택트럼 아날라이저 장비는 신호의 해석에 있어 진폭이 아닌 주파수 영역으로 신호를 해석하여 나타내는 방식 입니다. 문제는 이런 유형의 장비가 너무 고가(?) 이므로 아마츄어 무선사들이 사용하기에는 어려움이 많았습니다. ============== 이에 전세계 아마츄어 무선사들이 이 런 유형의 각 종 디지탈 장비와 와 s/w 를 이용하여  연구 하고 노력하고, 만들어 낸 제품이,  유럽의 햄인    Belarus 의 EU1KY YURY 입니다.....
