en.Wedoany.com Reported - VIAVI Solutions Inc. has introduced the TETRA MS radio base station simulator option for its field-portable CX300 Communications Service Monitor. This option enables complete testing without placing the radio in T1 test mode, simplifying and accelerating the verification of mission-critical communication systems.

TETRA (Terrestrial Trunked Radio) is a global open voice and data communication standard developed by the European Telecommunications Standards Institute (ETSI), operating independently of commercial cellular networks. Due to its resilience, fast call setup, built-in high-security encryption, group voice push-to-talk calls, and direct device-to-device communication via Direct Mode Operation (DMO), this standard has been widely adopted by industries such as emergency services, government agencies, and transportation.

This TETRA MS upgrade is available as a software key option for the CX300, requiring no additional hardware. It supports comprehensive testing of TETRA MS radios, including transmitter parameter measurements (power spectrum, RF power, carrier frequency offset, burst timing, modulation accuracy), call processing, and receiver BER/MER loopback, without needing to place the radio under test in T1 test mode. VIAVI also offers migration support for existing users of the legacy 3920B platform.

Wayne Wong, Director of Product Management for Radio Test at VIAVI, stated that VIAVI has been the benchmark for TETRA radio testing for over two decades, and the CX300 TETRA MS option represents the next step in this legacy. This upgrade allows technicians to test TETRA mobile stations as they operate in real-world scenarios, enabling registration to the base station without setting any special test modes on the radio.

The CX300 supports testing of all major LMR/PMR protocols, including TETRA, P25, DMR (MOTOTRBO), and NXDN. The device integrates spectrum analysis, signal generation and analysis, cable and antenna analysis, 2-port 1-path VNA, power measurement, audio analysis, and VIAVI AutoTest automatic calibration.

VIAVI (NASDAQ: VIAV) is a global enterprise in test and measurement and optical technologies. Its testing, monitoring, assurance, and resilient positioning, navigation, and timing solutions support and secure critical infrastructure, from data center ecosystems and communication networks to military, aerospace, railway, and first responder communications. Additionally, the company develops and advances technologies for high-volume optical applications in anti-counterfeiting, consumer electronics, aerospace, industrial, and automotive end markets.
