5 terms

tetra technical

"TETRA (terrestrial trunked radio), a global open standard for voice and data..."

Tetra is a prefix meaning “four,” used in medical, chemical and product names to indicate four parts, components or targets. For investors, spotting “tetra” signals that a drug, vaccine, device or product is designed to cover or combine four elements—like a four-blade fan covering more area—which can affect market reach, clinical testing complexity, regulatory scrutiny and potential revenue.

mer technical

"receiver BER/MER loopback without requiring the radio under test..."

The management expense ratio (MER) is the annual percentage fee a mutual fund or exchange-traded fund charges to cover its running costs and professional management. Think of it as a maintenance bill for an investment: a higher MER quietly reduces your returns over time, so investors compare MERs the way you'd compare fuel economy and upkeep when choosing between two cars—lower ongoing cost leaves more money working for you.

direct mode operation technical

"direct device-to-device communications through Direct Mode Operation (DMO)."

Direct mode operation is when a device, system, or production process runs using a straight, unmediated pathway—power, signals, or materials move directly without extra converters, buffering layers, or intermediary controls. Investors pay attention because direct operation often means higher efficiency, lower operating and maintenance costs, and fewer failure points, which can improve profitability and reliability, though it may reduce flexibility or demand stricter regulatory and safety controls.

dmo technical

"direct device-to-device communications through Direct Mode Operation (DMO)."

Debt Management Office (DMO) is the government agency that plans and carries out a country’s borrowing program, arranging the sale and repayment of government bonds and short-term bills. Investors watch DMO announcements and auction calendars because the amount and timing of government debt affect bond supply, interest rates and perceived fiscal risk—much like a household choosing when and how much to borrow can change loan costs and savings choices.

spectrum analysis technical

"The device integrates spectrum analysis, signal generation and analysis..."

A technique that breaks a complex signal, measurement or dataset into its component parts across a range (for example frequencies, wavelengths or risk factors) to reveal patterns, peaks or contaminants that aren’t obvious in the raw data. Think of it like taking a song apart to see each instrument so you can spot a sour note; investors care because it helps verify product quality, detect safety or compliance issues, and uncover hidden risks or signals that can affect value.

Allows full testing of TETRA MS radios, including transmitter parametric measurements, call processing and BER/MER loopback without the need to place radios in T1 test mode

CHANDLER, Ariz., June 15, 2026 /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has announced a TETRA MS radio base station simulator option for its field-portable CX300 communications service monitor. The upgrade enables full testing without placing radios in T1 test mode, streamlining and accelerating validation of mission‑critical communication systems.

TETRA (terrestrial trunked radio), a global open standard for voice and data communications developed by the European Telecommunications Standards Institute (ETSI), operates independently of commercial cellular networks. It has been widely adopted by emergency services, government agencies and industries such as transport for its resilience, fast call setup, built-in high security encryption, group-voice push-to-talk calling, and direct device-to-device communications through Direct Mode Operation (DMO).

The TETRA MS upgrade is available via a software-keyed option on the CX300 and requires no additional hardware. It enables the full testing of TETRA MS radios, including transmitter parametric measurements (power profile, RF power, carrier frequency offset, burst timing, modulation accuracy), call processing and receiver BER/MER loopback without requiring the radio under test to be placed in T1 test mode. VIAVI provides migration support for existing users of the legacy 3920B platform.

"VIAVI has been the benchmark for TETRA radio testing for more than two decades, and the CX300 TETRA MS option is the next step in that tradition," said Wayne Wong, Director of Product Management, Radio Test, VIAVI. "This upgrade lets technicians test a TETRA mobile station the way it actually operates in the field, registering to a base station without requiring any special test mode on the radio."

The CX300 supports the 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 automated alignment.
