AD2588 is a multi-channel precision testing instrument derived from AD2528. It is a true multi-channel audio analyzer. Equipped with standard 8-channel analog output and 8-channel analog input interfaces, it can achieve up to 8-channel parallel testing. The input channel can withstand a peak voltage of 160V, providing a more convenient and faster solution for simultaneous testing of multi-channel products. Production testing for multi-channel power amplifiers. In addition to the standard analog port, $r $nAD2588 can also be optionally equipped with various modules such as extended DSI0, PDM, HDMI, BTDUO, and digital interfaces.

AD2528 Audio Analyzer
Multi channel input artifact, retaining stronger expandability

Main functions and features:
Multi channel input/outputAD2528 supports 8 channels of simultaneous input, making it highly suitable for efficient testing on production lines and enabling easy implementation of multi-channel parallel testing. At the same time, the device also provides dual channel analog outputs and digital input/output ports, further enhancing its testing capabilities.
Independent and flexible configurationUsers can flexibly choose extension modules such as DISO, PDM, HDMI, and BT DUO according to their actual needs to meet different testing scenarios and requirements. This flexible configuration makes AD2528 a highly adaptable audio analyzer.
High precision testingThe key performance indicators of the equipment are good, such as residual THD+N of the signal source being below -106dB, ensuring the accuracy and reliability of the testing. Meanwhile, the analog input/output channels have extremely low flatness and residual THD+N, further improving the testing accuracy.
Complete and powerful electroacoustic analyzer functionsAD2528 is equipped with a complete electroacoustic analyzer function, supporting the output and measurement of multiple signal types, such as sine wave, dual frequency sine wave, out of phase sine wave, etc. In addition, the device also supports fast and comprehensive testing, which can be completed within 3 seconds, greatly improving testing efficiency.
Support multiple languages for secondary developmentThe device supports multiple languages such as LabVIEW, VB, C #, Python for secondary development, making it convenient for users to customize and optimize according to their actual needs.
