A²B Audio Transmission and Quality Testing Solution

● Through the Audio Analyzer A10 and A²B module, precise audio signal analysis can be conducted, including frequency response, THD+N, SNR and other key indices, ensuring high accuracy test results.
● The system supports up to 9 nodes (1 master + 8 slaves), and each node supports up to 32 audio channels of data acquisition and transmission, meeting testing needs of in vehicle A²B audio systems.
● Supports a wide signal output range (10 Hz to 23.952 kHz) and precise output accuracy (±0.00002 Hz), satisfying diversified A²B audio testing requirements.
● Detects audio signal quality in real time, providing spectrum analysis, time domain waveforms and other real time data feedback, helping users quickly discover and solve problems.
● Maximum supported A²B sampling rate of 48 kHz enables high quality audio signal acquisition, meeting modern high fidelity testing needs.
● THD+N can reach –190 dB, SNR up to –190 dB, ensuring low distortion and high fidelity during signal transmission.
● Supports no code automated testing; users only need to select and order test items, and the system automatically completes testing and generates reports, saving time and improving efficiency.
●  Workbench Mode suits real time signal analysis; Sequence Mode suits automated testing on production lines, ensuring flexible support in different scenarios.
● Supports multiple digital audio interfaces such as A²B, I²S, PDM, meeting connectivity requirements of in vehicle audio systems and other equipment, and supports AMC module for precise synchronization.
● Reports can be exported to PDF, Excel, CSV formats for subsequent analysis and sharing. All test settings and results can be managed via project files to ensure consistency and repeatability.
