Tetra tester improved
for maintenance tasks
Version 3.2 of the IFR 2968 radio test set includes a variety of new and enhanced automatic testing functions and extended Tetra interoperability profile coverage
Already the de-facto industry standard Tetra test tool for both basestation and mobile station installation and maintenance, IFR's Version 3.2 reinforces this leadership position. An active participant in the Tetra MoU, Tetra interoperability profile specification (TIP) and interoperability testing (IOP) activities, IFR's clear commitment to Tetra has also established the company as the principal supplier of Tetra wireless test equipment.

The IFR 2968 Version 3.2 is designed to provide faster, more comprehensive and easier to use tests for the routine terminal maintenance and repair operations normally undertaken by the emergency services and managed terminal suppliers.
Automatic receiver (BER) testing using 'TT' RF loopback enables the receiver sensitivity of the terminal to be tested automatically without the need for special test programs and interface connections or user intervention.
The Tetra equipment identity (TEI) is obtained automatically from the terminal and included in the test results to identify the terminal under test, avoiding the risk of human error.
The terminal's power class and receiver class are also obtained automatically so that the test program can apply the appropriate test limits.
Up to six different types of call setup and clear down can be specified in a built in test program to suit the capabilities of the terminal type to be tested and the degree of functional testing required.

Version 3.2 also includes extended TIP coverage including support for additional TIPv3 Part 1 core services, TIPv4 Part 6 air interface migration and TIPv4 Part 8 testing requirements.
TIPv3 Part 1 core services are supported in accordance with specification TTR 001-1 v3.0.13 including registration, individual call, group management, group call, emergency call, cell reselection, SDS status and telephone call.
TIPv4 Part 6 air interface migration is supported in accordance with TTR 001-6 v1.0.0 enabling Tetra terminals that support migration to register to the IFR 2968 regardless of whether the country code and network code configured in the terminal match the corresponding parameters configured in the test set.
This simplifies testing, particularly in cases where the terminal configuration is not known.
Test mode registration and Tetra test mode (TT) RF loopback are supported in accordance with TTR 001-8 v1.0.0 (TIPv4 Part 8) enabling Tetra terminals which support Tetra test mode to supply their equipment identity, power class and receiver class for test automation, as well as performing RF loopback for measuring receiver sensitivity using the bit error rate and message erasure rate.
Version 3.2 of the IFR 2968 radio test set will commence shipping in April 2002.
