Design, automate, and calibrate test systems spanning acoustic, RF, sonar, environmental, and structural domains - from software-defined instrument control to full production-line test automation. From single-instrument benchtop calibration to multi-domain, standards-compliant test lines, T3 open, modular test and measurement portfolio lets engineering teams build a procedure once and redeploy it across software-defined and fixed-function instruments alike, serving defense-grade acceptance criteria and university research labs alike across Vietnam and Southeast Asia.
T3 platform integrates hardware into unified test sequences, reducing manual test cycles while maintaining calibration traceability. Beyond standard LXI, VISA, RS-232, and GPIB instrument control, the platform natively handles non-standard interfaces.
T3 Test Automation Suite
T3 capability spans signal generation, reception, and analysis. Signal processing covers 20 Hz-200 kHz, supporting hydrophone calibration, acoustic absorption testing, and sonar performance prediction for defense, research, and communications applications.
Underwater Acoustic Recorder and Post-analysis
T3 covers simulation and validation of underwater pressure signatures. We support phased sensor qualification under combined-influence conditions, maintaining traceability suited to defense and research-grade underwater sensor programs.
Multi Influence Sensor Test Solution
T3 capability includes magnetic field strength measurement and magnetic-domain sensor qualification. We maintain ISO/IEC 17025 traceability and military acceptance criteria.
RF Test Set
Acquire, analyze, train on, and calibrate underwater acoustic signals - from submarine surveillance and maritime traffic monitoring to lab-grade transducer calibration - using one re-configurable, open-architecture system line built on off-the-shelf hardware. UROAS line shares a modular architecture across data acquisition, signal analysis, calibration, and training.

The UARP is a high-precision underwater acoustic reference system developed in Germany for the digital calibration and monitoring of hydrophones and acoustic projectors. Combining multi-channel hardware, an integrated reference signal generator, and the powerful TM06SW software suite, UARP delivers accurate, repeatable measurements for scientific research, marine surveys, and environmental monitoring. Its modular rack-based architecture and user-friendly operation make it a reliable, future-ready solution for demanding underwater acoustic applications.
Acoustic Analysis and Post-processing Software (VAAS) is an advanced solution for underwater acoustic signal processing, passive surveillance, and post-processing analysis. Designed for both live operations and mission replay, VAAS transforms raw underwater sound into actionable intelligence.
The LF-500 is a comprehensive low-frequency sonar testing system that simulates and validates active and passive sonar performance under real marine conditions. It collects critical data, such as reverberation, ambient noise, sound speed, and depth, while evaluating self-noise from both sonar systems and vessels. The system calculates key acoustic parameters, including attenuation and reflection losses, and supports active and passive calibration for transmitter power, frequency, and receiver sensitivity, enabling precise, mission-ready performance validation and modeling.
The Sonar Calibration System is used to test, calibrate, and simulate naval sonar systems by generating, receiving, and analyzing underwater acoustic signals. It enables accurate sonar performance validation, operator training, and system calibration in both laboratory and real sea conditions.
An open-architecture test executive for automated instrument control and test sequencing across laboratory and production environments. T3 software is extensible by design, hardware-agnostic by architecture, and built to integrate with the instruments your programme already uses.
T3 Test Automation Suite is a standalone, instrument-agnostic automation and lab-management platform. Any device controllable over LXI, VISA, RS-232, or GPIB plugs into one sequencing, data-capture, customized procedure and reporting layer. Deployed in production at 30+ university and research institute labs across Vietnam.
