Test and measurement for broadcasting

ETSI EN 303 340에 따른 디지털 지상파 TV 방송 수신기 테스트

2017년 6월 이후 유럽 연합에서 판매 또는 사용하는 거의 모든 무선 송신기 및 수신기는 인접 주파수 대역의 간섭 신호에 대한 면역성을 테스트해야 합니다. ETSI 표준 EN 303 340에 디지털 TV 수신기에서 수행해야 하는 테스트와 합격 조건이 정의되어 있습니다.

이 애플리케이션 노트는 테스트 절차에 대해 설명하고 R&S®BTC Broadcast Test Center의 save-recall file 및 간섭 신호에 대해 말씀드립니다.

Test of Digital Terrestrial TV Broadcast Receivers according to ETSI EN 303 340 | 1GP116

Starting from June 2017, almost all radio transmitters and receivers sold or put into operation in the European Union have to be tested for immunity against interferers in adjacent frequency bands. ETSI standard EN 303 340 defines the tests to be performed on digital television receivers and requirements to be passed.

This application note describes the test procedures and provides save-recall files and interferer signals for the Broadcast Test Center R&S®BTC.
