The audio analyzer designed specifically for the needs of hearing instrument manufacturers.","The APx511 Hearing Instrument Audio Analyzer is designed to meet the needs of hearing instrument manufacturers, providing the specific measurements and I\/O required for hearing instrument production test, delivered with Audio Precision’s reputation for high performance and reliability.","All APx models use the same software, so with the R&D department using an APx525 or APx585 and APx511 deployed on production lines, product design is faster, interaction between Engineering and Production is easy and the AP report generated by Quality Control is trusted around the world. IEC60118-7 \/ ANSI S3.22 function library","APx511 supports a .NET library of functions that automate the tests described in IEC60118- 7 and ANSI S3.22. For the production environment, these functions can be called from any .NET capable language or LabVIEW to control the APx511’s output and measurement settings.","For troubleshooting or test setup, the APx511 can be controlled by the standard APx500 software providing a rich graphical user interface and access to automated reporting, real-time signal monitors, high resolution FFTs and controls for limits & other settings.","In addition to standard audio tests such as level, distortion, frequency response, and attack & release, APx511 can measure battery current using its built-in battery simulator circuit.","Built-in support for test chamber speaker, telecoil & microphone","The APx511 generator includes an in-line 2 watt loudspeaker amplifier (8 ohms) and a telecoil amplifier, allowing >110 dB SPL and up to 400 mA\/m field strength from 100 Hz to 10 kHz in a test chamber such as the Interacoustics TBS25. On the input side, APx511 supplies 24 V DC of constant current through a single BNC for a pre-polarized measurement microphone.

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
