音频放大器和前置放大器

APx515是为生产测试优化的高性能音频分析仪。APx515具有典型的THD+N为–106 dB、具有24位分辨率的100万点FFT和192K数字I/O。它以其速度、性能、自动化和易用性是一流的仪器。APx515是一款重要的产品，因为它以生产级的价格提供音频精度的性能和可靠性。，APx是世界上速度最快的音频分析仪，在1.2秒内返回21个音频测量值。它也是最容易使用的，具有一键式测量、自定义报告和复杂的自动化，无需任何编程。还提供了完整的API和LabVIEW驱动程序。，这种速度和易用性意味着测试永远不会成为瓶颈，生产线经理可以获得可靠、一致的结果，与当前的低成本替代品（如失真分析仪）相比。，对于外包生产的公司，要求APx515进入生产线，可以更严格地控制生产，确保制造商满足合同要求。

High measurement speed, parallel signal processing in multichannel applications, and high reliability in continuous operation are vital requirements to be met by audio analyzers for use in production. If, on top of that, a cost-efficient instrument for system use is what you need, the solution is the R&S®UPP audio analyzer.","The R&S®UPV audio analyzer – the high-end instrument from Rohde & Schwarz – has held a solid position in all audio T&M applications for years. Measurement accuracy and dynamic range at the limits of what is possible, combined with unique measurement capabilities, make the R&S®UPV ideal primarily for research, development and quality assurance tasks.","Many audio applications do not place such high requirements on dynamic range and versatility. The emphasis in production is often on high throughput, and the cost of production test assemblies also plays a major role. When testing consumer audio equipment, multichannel devices of surround-sound systems must also be measured using state-of-the-art interfaces such as HDMI. This is where the R&S®UPP audio analyzer family comes into its own. Depending on the model, two, four or eight channels are processed in parallel; and by cascading multiple instruments, users can simultaneously trigger up to 48 measurement channels, which cuts down on measurement time.","The compact cost-efficient R&S®UPP audio analyzer is designed for system applications. It features low height, and comes without front-panel control elements or integrated display. The instrument can be remote-controlled via LAN, USB or IEC\/IEEE bus. In combination with an external monitor, mouse and keyboard, it becomes a manually operable measuring instrument for a lab bench. It has an integrated control PC, and the required software is already installed. Users can start taking measurements right away.","Featuring the same operating philosophy and remote control, the R&S®UPV and R&S®UPP audio analyzers are a strong team: They provide the optimal solution for both R & D and production, respectively, and harmonize well together, for example when instrument settings or measurement routines have to be exchanged.","Key Facts
