![Introduction of Development Case! [Mixed Signal Test System]](https://image.mono.ipros.com/public/product/image/664/2000058709/IPROS4140417814692552792.jpg?w=280&h=280)
This is an introduction to the achievements of semiconductor testing equipment [Mixed Signal Test System].
We will fully support your development. Our design engineers will take into account the electrical conditions and have the capability to respond to delivery schedules, providing comprehensive support for your development.
ITU-T P.1140 is a voice quality testing system for emergency call (eCall) devices (broadband).
In the event of a car accident, the emergency call system will automatically dial the emergency call center hands-free. To ensure optimal call quality between the car and the response service, the ITU-T specifies a comprehensive testing method for hands-free emergency calls originating from cars in ITU-T Recommendation P.1140. HEAD acoustics has commercialized tests for wideband (WB) calls as the ACQUA standard specification UG P.1140-WB. The ACQUA standard covers the wideband part of ITU-T Recommendation P.1140 (07/2022).
The Standardization Administration of China has established a comprehensive testing standard for voice calls during emergency notifications as GB/T 45314-2025.
The ACQUA standard specification GB/T 45314 eCall has been developed and commercialized to implement the acoustic performance compliance verification tests and requirements for narrowband and wideband voice transmission based on GB/T 45314-2025 (Clause 5). All voice signals used in acoustic measurements are in Chinese. The ACQUA standard specification consists of a single ACQUA project, which includes the measurement and analysis of eCall systems capable of processing narrowband and wideband signals. This project has implemented testing and result analysis tools based on the requirements of GB/T 45314-2025 (Clause 5).
