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

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.
