APx585B Series Audio Analyzer
Eight-Channel Modular Audio Analyzer
The APx585B Series is a true multichannel audio analyzer, with eight simultaneous analog outputs and inputs. It's ideal for designing and testing consumer devices such as home theater receivers or pro devices like mixing consoles.
Excellent performance, with source distortion as low as -120dB
The core competitiveness of the APx555B ADC/DAC testing solution lies in its unparalleled source distortion performance. In precision measurement, source distortion is one of the key indicators to measure the performance of converters, which directly affects the purity of signal conversion. APx555B, with its advanced internal architecture and precise calibration technology, has achieved astonishing performance with typical source distortion values as low as -120dB, which far exceeds the industry average and provides a solid guarantee for high-precision measurement.
DC bias, flexible response to complex requirements
In the application of high-performance analog sources, how to effectively add and control DC bias has always been a challenge faced by engineers. Traditional methods often require the addition of complex circuits externally to achieve, which not only increases the complexity and cost of the system, but may also introduce additional noise and distortion. The APx555B innovatively features a built-in DC bias function, allowing users to directly set the desired DC bias voltage on the device without the need for additional hardware support. This design not only simplifies the system architecture, but also ensures that adjusting the DC bias will not have any negative impact on the overall performance of the analog source, making it an ideal choice for handling complex signal scenarios.
Comprehensive testing to assist in product optimization and upgrading
The APx555B testing solution is not limited to excellent performance in source distortion and DC bias, but also provides comprehensive testing capabilities, including precise measurement of key parameters such as dynamic range, signal-to-noise ratio, and total harmonic distortion. The integration of these functions enables engineers to conduct comprehensive evaluations on one platform, quickly identify problems, and optimize design solutions. At the same time, APx555B also supports multiple communication interfaces and flexible testing configuration options, which can meet the testing needs of different application scenarios.
