Radio test set

Wednesday, 30 June, 2004 | Supplied by:

Vicom has expanded the functionality for the 2975 Radio Test Set for Project 25 (P25) testing from IFR, a designer of advanced test solutions that include wireless radio test sets, signal sources, avionics and frequency agile test, microwave test, signal analysers and ATE (automated test equipment).

Firmware upgrades can be loaded directly into the test set via the Internet and the options can be enabled in the field.

Options include: advanced encryption system (AES); encryption key management; linear simulcast modulation P25 Phase II CQPSK; VHF/UHF P25 trunking; control channel logging; P25 trunking protocol; and 900 MHz band option.

The 2975 is a digital radio test platform that tests radio equipment to ensure compliance under the Project 25 standards, including parametric testing for compatible four-level frequency modulation (C4FM) and interoperability testing of P25 systems. Providing independent 'generate and receive' functions from 1 MHz to 2.7 GHz, it allows duplex operation over a full instrument range. This enables a wide variety of system configurations to be tested including cross-band repeaters. Additionally it has two audio-function generators to support conventional FM terminal testing.

Created with a modular design, the test set is simple to support and upgrade. Its 20 GB internal hard drive and 3.5" floppy drive simplify program installation and maximise flexibility in storage and recall of set-up information and test data. Software upgrades can be downloaded, allowing features to be added as new radio-specific tests are developed, reducing ownership and life cycle costs.
