Electromagnetic compatibility and Radio spectrum Matters (ERM) - Radiotelephone transmitters and receivers for the maritime mobile service operating in VHF bands - Technical characteristics and methods of measurement
The present document specifies the minimum requirements for shipborne radio transmitters and receivers for fixed installations operating in the VHF frequency bands between 156 MHz and 174 MHz allocated to the maritime mobile service, using both 25 kHz and 12,5 kHz channels and capable of Radiotelephony and Digital Selective Calling communications within the Global Maritime Distress and Safety System. The present document incorporates the requirements of the relevant resolutions of the International Maritime Organization (IMO) and is primarily intended to specify equipment suitable for fitting to ships subject to the SOLAS Convention [1] and complying with the Council Directive 96/98/EC [i.11] of 20 December 1996 on marine equipment as amended (the European Marine Equipment Directive). The present document does not address the testing of ancillary equipment on a stand-alone basis, i.e. separately from the
radio equipment with which it is to be used.
Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Radiotelefonski oddajniki in sprejemniki za pomorske mobilne storitve, ki delujejo v pasovih VHF - Tehnične karakteristike in merilne metode
Ta dokument določa minimalne zahteve za stacionarne ladijske radijske oddajnike in sprejemnike, ki delujejo v frekvenčnih pasovih VHF med 156 MHz in 174 MHz, dodeljenih pomorskim mobilnim storitvam, ki uporabljajo tako kanal 25 kHz, kot tudi 12,5 kHz in znotraj globalnega pomorskega zasilnega in varnostnega sistema omogočajo komunikacijo prek radiotelefonije in digitalnega selektivnega klica. Ta dokument vsebuje zahteve zadevnih resolucij Mednarodne pomorske organizacije (IMO) in je v prvi vrsti namenjen določitvi opreme, primerne za ladje, skladne z uredbami Mednarodne konvencije o varstvu človeškega življenja na morju (SOLAS) [1] in spremenjeno Direktivo Sveta 96/98/EC [i.11] z 20. decembra 1996 o pomorski opremi (evropska direktiva o pomorski opremi). Ta dokument se ne nanaša na preskušanje samostojno stoječe dodatne opreme, tj. ločeno od uporabljene radijske opreme.
