The type approval test system for trunked mobile radio terminals certification purposes allows the conformance analysis of the radio terminal according to MPT1323 and ETS 300 086 in the case of conventional ones.

Iberlab/UX is the software platform used as the test engine core application.

The test system arquitecture responds to the traditional configuration used for conventional mobile radio testing, although with some minor modifications.

The stimulus subsystem is composed by three RF signal generators to simulate three simultaneous control/traffic channels in the network.

These RF sources can be either modulated by internal LF generators, external LF generators or signaling FFSK generators depending on the nature of the channels that the system should simulate for a given test.

The analysis subsystem considers:

a power meter,
a spectrum analyzer,
a modulation analyzer/receiver,
an audio analyzer,
a digital waveform recorder,
a FFSK signaling receiver
and broadband RF directional detectors.
RF and LF signals are routed by means of a switching unit, which also includes signal conditioning elements.

The system is completed with a DC linear power supply.

Currently, the system is being used by the Certification Laboratories of Telefónica and the Secretaria de Telecomunicaciones (Science & Technology Spanish Ministry).
