Radio tester integrates TETRA II system

Aeroflex Inc., a wholly owned subsidiary of Aeroflex Holding Corp., and fjord-e-design GmbH announced the first implementation of a TETRA II test system on a portable radio tester, the Aeroflex 3920 Digital Radio Test Set. The test solution allows transmitter and receiver testing of base stations and mobile stations supporting the TETRA Enhanced Data Service (TEDS).

In the implementation, Aeroflex and fjord e-design demonstrated TEDS Frequency Division Multiplexing (FDM) signals with 64QAM modulation and 8 sub-channels in a channel bandwidth of 50kHz being generated and analyzed, including the generation and analysis of the defined T4 test signal per the European Telecommunications Standards Institute (ETSI) TEDS standard.

The new option for the 3920 Digital Radio Test Set was developed in a joint project with fjord-e-design, a TETRA focused, engineering company located in Flensburg, Germany. fjord e-design offers reference-class protocol stacks for TETRA and other Private Mobile Radio (PMR) standards to the industry.
