The present document is part 1 of a multi-part deliverable covering the Ground-based VHF hand-held, mobile and fixed radio transmitters, receivers and transceivers for the VHF aeronautical mobile service using amplitude modulation, as identified below: Part 1: “Technical c

34、haracteristics and methods of measurement“; Part 2: “Harmonized EN covering essential requirements of article 3.2 of the R - if equipment available on the market is required to be checked it will be tested in accordance with the methods of measurement specified in the present document.

35、300 676-1 V1.5.2 (2011-03) 91 Scope The present document states the minimum performance requirements for radio transmitters, receivers and transceivers at ground-based aeronautical stations operating in the VHF band (118 MHz to 136,975 MHz) allocated to the aeronautical mobile service. In situations

36、 where transmitters and receivers are located in close proximity there is the possibility of interference. In such cases, external filters and isolators may be necessary as part of the installation to achieve an isolation performance in excess of the minima defined in the present document to overcom

37、e the interference. The present document applies to DSB AM systems, with channel separations of 8,33 kHz or 25 kHz intended for analogue speech and ground base stations with a channel spacing of 25 kHz intended for ACARS data communication. NOTE: The test methods and procedures in the present docume

38、nt may also be used to show technical acceptance for radio transmitters, receivers and transceivers at ground based aeronautical stations operating with 25 kHz channel spacing in the extended VHF bands (108 MHz to 117,975 MHz and 137 MHz to 155,975 MHz). The scope of the present document is limited

39、to ground base stations, ground mobile and hand held radios for ground use. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
