BS EN 62002-2:2008Mobile and portable DVB-T/H radio access. Interface conformance testing
Part 2 of BS EN 62002 provides the conformance testing rules and guidelines for equipment built to meet the Mobile and portable DVB-T/H radio access interface specification (IEC 62002-1).
One aim is to limit the number of tests to a practical level. Nevertheless, the manufacturer is responsible of guaranteeing that the terminal fulfils all aspects of the mobile and portable DVB-T/H radio access interface specification (see IEC 62002-1).
The text of document 100/1290/CDV, future edition 2 of IEC 62002-2, prepared by IEC TC 100, Audio, video and multimedia systems and equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62002-2 on 2008-06-01.
BS EN 62002-2:2008 supersedes EN 62002-2:2006 which has been withdrawn.
The main changes with respect to EN 62002-2:2006 are listed below:
- DVB-H has been included as a part of the main specification
- All the performance figures have been revised as new simulation results have been made Available as well as new reference receivers for DVB-H have been developed
- DVB-H now includes all the different MPE-FEC code rates
- New portable indoor and portable outdoor channel models have been included as well as performance figures for those
- A new 2x TU-6 mobile SFN test channel has been included
- A new L4 linearity pattern has been added
- Dedicated performance figures for DVB-H for S1, S2, L1 to L4 interference patterns have been included
- New GSM-interference measurement method has been added.
- An annex has been added by CENELEC.
