ADLINK's PCIe-9529 24-bit high-precision signal acquisition module with dynamic range up to 110dB and eight input channels easily meets multi-channel vehicle navigation testing requirements, measuring Signal-to-Noise Ratio (SNR), THD+N, channel crosstalk, volume, primary frequency, and items. Eight 24-bit sampling analog input channels mean the PCIe-9529 can simultaneously measure two 4-channel devices, and included LabVIEW drivers allow quick development of in-house testing programs. As shown, PCIe-9529's eight analog input channels connect to two DUT soundtracks, after which FFT is used to obtain testing values including SNR, THD+N, dynamic range, and others, to effectively and quickly determine whether the DUT conforms to specific requirements.
Users can benefit greatly from ADLINK's PCIe-9529 multi-channel signal acquisition module, with shorter testing, improved efficiency, and significant time and manpower reduction, all with no requirement for expensive audio analyzers, thus significantly reducing overall costs of testing. With eight 24-bit sampling analog input channels, the PCIe-9529 can test two 4-channel devices simultaneously, shortening test cycles and enhancing efficiency. The SDKs support C/C++, .NET and LabVIEW, allowing quick development of required audio testing systems for automated production line testing, reducing time, effort, and cost.
