• IoT communication protocols, such as Bluetooth, Lora, Zigbee, Z-Wave, e-MTC, NB-IoT, UWB, etc.

Support common instruments and meters for OTA testing, including domestic and international mainstream spectrum meters, network analyzers, synthesizers, signal generators, etc., to complete signalling and non-signalling tests.

# 02 Fast testing

With the increase in test standards and test specifications, OTA test systems are taking longer and longer to operate, seriously affecting product commissioning time. At the same time, traditional MPAC technology can no longer meet the needs of 5G NR testing.

Libra has its own intellectual property rights in Raytest fast test technology. The technology enables fast TIS scanning and reduces SISO test time by 84%.

Libra has its own patented technology, Radiated Two Stage (RTS), which mechanically solves the efficiency problem of MPAC testing for 5G NR and reduces the MIMO throughput testing time by 69%.

# 03 Test process automation

A complete OTA test task contains a lot of content, and abnormalities are common during the test process, which often requires manual watch and frequent intervention, which is time-consuming and laborious.

Libra adopts a workflow concept to support batch test task scheduling. By setting flexible exception handling strategies (e.g. anti-dropout, breakpoint renewal, etc.), it enables unattended continuous operation, which greatly improves system utilisation and reduces operational costs.

To ensure correctness and accuracy, OTA test systems need to be calibrated periodically, Libra integrates automated calibration functions and supports mainstream instruments in the market, simplifying the system calibration process and reducing operational difficulties for users.

# 04 Test function customisation

OTA test software should have good system scalability and be able to respond flexibly and quickly to changing industry needs, such as testing methods, adjusting test specifications, changing test equipment, and even integrating with customers’ proprietary business systems.

With its modular design and scalable system architecture, Libra can quickly support new communication standards and test specifications, adapt to field instruments and complete integration with independent systems (e.g. OA, CRM, ERP, MES, etc.) while fully supporting standard methods and equipment, meeting the user’s needs for flexible customisation of test processes and creating value for the customer.

# 05 Diversification of results analysis

The OTA testing process is complex, generates large amounts of data and makes analysis of test results difficult. A comprehensive, fast and intelligent analysis aid is an indispensable aid for professionals.

Libra has designed comprehensive information recording and result analysis functions from the user’s perspective, supporting 3D testing, 2D testing with optional planes, single point testing, monitoring and recording of the entire testing process, as well as diverse report analysis, 2D and 3D arbitrary angle rotation browsing and cutting functions and other comprehensive data analysis, diagnosis and traceability functions, assisting R&D engineers to quickly analyse and diagnose problems.

# 06 High safety factor

Security is the lifeblood of industrial software. To cope with complex deployment environments and application scenarios and to protect customers’ business secrets and private information from theft and leakage, Libra provides multi-layered protection measures in both hardware and software.

• Application and test data protection based on industrial-grade encryption locks: a hard locking authorisation scheme prohibits the opening of test software without a lock, enabling mandatory authorisation; based on high-strength shelling technology to prevent the intrusion of malicious applications and Trojan horses, ensuring the integrity and trustworthiness of test programs; ensuring that test data can only be accessed in a controlled range to avoid information leakage.
• Identity-based system authentication and 360° system audit log: add a user authentication system (optional) to the hard lock protection to prohibit illegal access to the system, strictly control the black and white list of soft operators for OTA testing, and execute a comprehensive behaviour log for authorised users to meet audit compliance. Supports integration with users’ internal systems (e.g. OA systems) to meet their internal control requirements.

# 07 Good user experience

Libra is a professional industrial grade OTA testing software, UX/UE adopts the design concept and interaction method of Internet program, combining the advantages of industrial software and domain software, combining the traditional and advanced, bringing users a new experience.

• The Libra user interface is fresh and simple, the functions and features are well organised and the operating procedures are clear at a glance, providing the ultimate in comfort and productivity.
• The Libra test configuration is clear, the performance is stable and the system is compatible, providing a smooth and reliable operating experience for users.

Libra test software fully supports the GTS multi-probe OTA test system, including RayZone® 1800, RayZone® 2800, RayZone® 8000, RayZone® 9000 and other series of products, and has been recognized and favored by a large number of users at home and abroad.
