APx515 오디오 분석기

APx515 2 채널 오디오 분석기

생산 테스트 및 엔트리 레벨 R & D 애플리케이션에 이상적

APx515는 생산라인 테스트를 위해 최적화 된 고성능 오디오 분석기입니다. APx515는 일반적으로 -106dB의 THD+N, 24bit 해상도의 백만 포인트 FFT, 192K 디지털 I/O를 가지고 있습니다. 속도, 성능, 자동화 그리고 사용자 편리동급 최강입니다.

APx515는 원가 수준의 가격으로 Audio Precision의 신뢰성과 성능을 제공해주는 특별한 제품입니다.

APx는 전 세계에서 가장 빠른 오디오 분석기입니다, 1.2초 만에 21가지 오디오 측정이 완료됩니다. 원클릭 측정으로 사용하기 쉽고, 사용자에 의한 레포트 생성과 프로그램밍 없이 수준 높은 자동화가 실행됩니다. 또한 완전한 API와 LabVIEW 드라이버가 제공됩니다.

이러한 신속성과 사용 편리성은 테스트의 병목현상이 전혀 없고, 생산라인 관리자는 신뢰성을 확보하고 안정적인 결과 디스토션 분석기와 같이 통용되는 저가형 대안과 비교 되는 안정적인 결과를 얻을 수 있습니다.

생산을 아웃소싱한 업체에서, 생산과정을 더 엄격한 관리하는 생산라인에서 APx515를 필요로 하며, 제조사들은 그들의 계약서상의 요구사항을 만족시킬 수 있습니다.

저렴한 가격으로 쉬운 자동화와 3초 만에 이루어지는 종합적인 테스트
APx515는 사용자 인터페이스에 의해 독립된 테스트 유닛으로 동작하거나 .NET 또는 LabVIEW 어플리케이션에 의해 컨트롤 할 수 있습니다. 각 각의 경우, 작업자는 키보드, 풋 컨트롤러 또는 바코드 스케너를 사용하여 APx를 컨트롤 하거나, 시스템을 완벽히 자동화 할 수 있습니다. 스위처와 pass/fail 점등기와 같은 외부 기기도 지원합니다.

독립 모드에서 수준 높은 테스트 시퀀스는 코딩이 필요없는 일반적 오디오 측정 항목을 선택하여 생성시킬 수 있습니다. Pass/fail 리미트, 진보된 구성 그리고 사용자 프롬프트는 필요에 따라 추가 할 수 있습니다. 그런 후에 레포트 형식은 Microsoft Word를 이용한 그래프를 출력하거나 CSV 파일로 저장할지 선택합니다. 프로젝트는 생산라인에서 변경하는 것을 방지하기 위해 잠금 설정을 할 수 있습니다.

자동화된 라인에서, .NET 또는 LabVIEW 어플리케이션은 API나 APx LabVIEW 드라이버를 이용하여 APx515를 직접 컨트롤 할 수 있습니다. 개별적인 측정은 별도로 실행하거나 마스터 어플리케이션으로 APx UI를 이용하여 생성된 테스트 시퀀스를 불러올 수 있습니다.

Code-Free Automation & Complete API
APx500 Measurement Software is the most advanced audio measurement interface available. Complex procedures that include user prompts, limits, and calls to external applications can be created directly in the GUI, saving time and money while ensuring painless updates over time, as no development is required.

Create custom interfaces and application-to-application automation using the comprehensive APx API for integration in VB.NET, C#.NET, MATLAB, and LabVIEW development environments. Projects and automation can be shared with other APx units anywhere in the world.

Common Software Platform
From a practical perspective, all APx audio analyzers use the same software, making tests and results easier to share. All settings for a test are saved in a single project file, making it easy to replicate test setups between R&D and production facilities anywhere in the world. Project files are compatible with all APx instruments and each project is self-contained, so there’s never any worry about dependencies or broken links. Users can even embed waveform files and images within a project file.

For customers, contract manufacturers or management, APx automatically generates rich graphic reports, with highlighted pass / fail limits and options to export as PDF, HTML, Excel, CSV, RTF or MATLAB files.

Digital Protocol Analysis
Modern consumer devices such as televisions, Blu-ray players, and receivers typically use a digital interface such as S/PDIF, Toslink, HDMI to transmit audio signals.  In addition to the digital audio data, these interfaces also carry auxiliary information about the audio signal, metadata. The APx Metadata monitors decode and display metadata values as they are received from the device under test.

 

 

I/O OPTIONS

AES/SPDIF (APx515 standard)
Provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O.

ASIO (APx515 option)

SOFTWARE

APx500 software options provide measurements and functionality beyond the core set of capabilities standard for the APx515. A variety of options are offered, suited to different specific test applications and requirements.

Software options are enabled by one or more “iButtons” that mount on the rear of the APx515. Each iButton enables a particular feature or set of features, and can be moved from analyzer to analyzer as needed.

Electro-Acoustic Production Test (SW-SPK-PT)
The SW-SPK-PT option enables high-speed production test of electro-acoustic devices, providing key loudspeaker measurements in a single one-second sweep.
