Latest updates are available on the ETSI Web server (http://webapp.etsi.org/IPR/home.asp). All published ETSI deliverables shall include information which directs the reader to the above source of information. Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). For non EU countries the present document may be used for regulatory (Type Approval) purposes. The present document is part 1 of a multi part deliverable, covering digitally modulated Radiosonde transmitters in the Meteorological Aids frequency band from 400,15 MHz to 406 MHz, as identified below: Part 1: "Technical characteristics and test methods"; Part 2: "Harmonized EN covering essential requirements under article 3.2 of the R&TTE Directive". Clauses 1 and 3 provide a general description on the types of equipment covered by the present document and the definitions and abbreviations used. Clause 4 provides a guide as to the number of samples required in order that type tests may be carried out, and any markings on the equipment which the manufacturer should provide. Clauses 5 and 6 give guidance on the test and general conditions for testing of the device. Clause 7 gives the maximum measurement uncertainty values. Clause 8 specifies the spectrum utilization parameters which are required to be measured. These are the maximum limits which have been chosen to minimize harmful interference to other equipment and services. The clause provides details on how the equipment should be tested and the conditions which should be applied. Annex A provides specifications concerning radiated measurements.
Annex B provides information on the spectrum analyser specification. Annex C provides related bibliography information.

1 Scope The present document applies to digitally modulated Radiosonde transmitters and whole units in the range from 400,15 MHz to 406 MHz and with power levels ranging up to 200 mW. The present document shall not be applied to the presently widely used analogue FM Radiosonde transmitter.
The present document contains the technical characteristics for radio equipment referencing CEPT/ERC/REC 70-03 [2]. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. It is a product family standard which may be completely or partially superseded by specific standards covering specific applications. For non-harmonized parameters, national regulatory conditions can apply regarding the type of modulation, channel/frequency separations, maximum transmitter output power/effective radiated power, equipment marking and the inclusion of an automatic transmitter shut-off facility as a condition of the issue of an individual or general licence, or, as a condition of use under licence exemption. The extreme atmospheric conditions are given in clause 5.4.4 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
