APx555 오디오 분석기

APx555 고성능, 모듈 형 2 채널 오디오 분석기

새로운 표준 - 오디오 분석 성능과 다양한 기능

30년간 정상에서 오디오 산업의 표준으로 인정받는 테스트 장비를 만들어 온 노하우로 제작된 APx555는 한 치의 오차도 허용하지 않은 완벽한 분석기입니다. 최고의 성능과 넓은 영역의 디지털 I/O 옵션, 빠르고 직관적인 어를 필요로 하는 R&D 엔지니어와 생산라인 기술자들을 위해 개발된 APx555는 오디오 분석기의 새로운 표준입니다.

오디오 분석기의 완벽한 진화
APx555는 성능과 호환성 그리고 다양한 능력을 제공합니다.

역사상 유래가 없는 성능
일반적으로 1MHz까지의 잔류 THD+N가 -120dB이며, APx555는 SYS-2722 분석기와 비교하여 5dB가 개선된 것을 포함하여, 다른 모든 오디오 분석기의 아날로그 성능을 능가합니다. 24bit 해상도로 1.2M 포인트의 FFT 뿐만 아니라, 다른 어떤 장비와 비교할 수 없는 성능을 경험하게 될 것입니다.

다양한 I/O
APx555 는 2개의 밸런스와 2개의 언밸런스 아날로그 입력과 출력, AES/EBU, TOSLINK, 그리고 SPDIF를 포함한 192K 디지털 입력과 출력을 지원합니다. 추가로 Digital Serial, ARC를 포함한 HDMI, PDM, 블루투스 옵션을 통해 I/O를 확장시킬 수 있습니다. 새로운 Advanced Master Clock(AMC) 모듈은 외부 장비와 APx555를 동기시키기 위해 클럭 신호의 입출력을 가능하게 해줍니다. AMC는 APx555는 기본 사양이며, APx52x 와 APx58x 시리즈는 옵션입니다.

소프트웨어 유연성
새롭게 디자인 된 소프트웨어 플랫폼으로, APx 시리즈는 이제껏 볼 수 없었던 강력하고 뛰어난 호환성과 유용성을 제공합니다. 과감하고 새로운 인터페이스는 사용하기 쉬운 두 가지 모드를 사용자에게 제공합니다. 빠른 생산라인 테스트와 자동화 측정을 위한 시퀀스 모드와 다양한 파라메터에 대한 디바이스의 반응을 실시간으로 보여주는 벤치 모드를 선택하여 사용할 수 있습니다.

파워 앰프 설계자를 위한 측정
연속적인 최대 출력과 피크 최대 출력의 자동 측정, DIM 측정, 조정된 주파수 스윕을 이용한 파워 스펙트럼 그래프 보기, 그리고 CEA-2006와 CEA-490A 표준에 의해 규정된 다른 측정 수행. 일반적인 동위상 노이즈 제거 능력 측정뿐만 아니라, APx555 또한 IEC60268의 섹션 14.15.1 에 따른 CMRR 측정이 가능합니다.

프로젝트 공유
전세계 어디서든 R&D와 생산설비 간에 테스트 설정을 쉽게 복제하고, 모든 설정값은 이메일을 통해 전송이 가능할 만큼 작은 용량의 하나의 프로젝트 파일로 저장이 가능합니다. 프로젝트 파일들은 모든 APx 장비에서 호환되며, 각 프로젝트는 자체적으로 독립된 것이므로 링크가 깨지거나 종속 등에 대해 걱정할 필요가 없습니다.

결과 레포팅
고객들과, 계약된 제조업체들 또는 관리 업체들을 위해, APx는 Pass / Fail 리미트가 적용된 그래프 형태의 레포트를 자동으로 생성하고, 옵션으로 PDF, HTML, Excel 또는 Text로 저장이 가능합니다.

Jitter Analysis
Jitter in digital audio systems may cause audible distortion in the form of jitter sidebands in the output signal. Jitter tolerance testing can reveal jitter induced distortion but is often neglected in the design of circuits and components because it is difficult and time consuming. Audio Precision APx analyzers provide jitter generation and jitter analysis features to simplify jitter testing.

Made to Measure for Power Amp Designers
Measure continuous maximum output and peak maximum output automatically, DIM measurements, view power spectrum graphs with a regulated frequency sweep and take other measurements as specified by the CEA-2006 and CEA-490A standards. In addition to conventional balanced common mode rejection measurements, APx555 also enables CMRR measurements in accordance with IEC60268 section 14.15.1.

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.

Advanced Digital I/O (standard)
Provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O. The APx ADIO module enables the generation of advanced impairments for sophisticated test of devices via AES/SPDIF/TOSLINK. It also includes the Advanced Master Clock (AMC) module, which handles input and output clock signals for synchronizing an APx with external equipment (or vice versa). AMC also provides jitter generation and measurement functionality for jitter-enabled I/O modules such as ADIO, DSIO and PDM.

ASIO (standard)
PC audio interfaces with installed ASIO drivers appear within the APx500 software as one of APx’s I/O options, with support for up to 16 bidirectional channels. All measurements and test sequences in APx may be used via the ASIO interface, allowing for complete characterization of the connected audio device.

Bluetooth (option)
APx’s Bluetooth module, with built-in radio and software stack, allows engineers to measure their Bluetooth devices directly. All Bluetooth controls are integrated into the analyzer software and APx supports A2DP, HFP 1.6, and AVRCP profiles. Codec support includes SBC, aptX, CVSD, and wideband speech (mSBC).

Digital Serial I/O (option)
Digital serial capability is essential in R&D for evaluating designs at the circuit board level. The Digital Serial I/O (DSIO) option provides a direct multichannel connection to chip-level interfaces such as I2S, TDM, and other popular serial interface formats including left-justified, right-justified, and DSP. Jitter capable.

HDMI + ARC (option)
The APx HDMI option allows engineers to measure HDMI audio quality and audio format compatibility on devices such as surround sound receivers, set-top boxes, smartphones, tablets, TVs, and DVD or Blu-ray Disc™ players. APx can stream both lossless and compressed formats from pre-encoded audio test files, making it easy to troubleshoot component compatibility and issues related to downsampling, downmixing, or transcoding.

PDM (option)
The APx PDM option provides direct connectivity for audio devices that have a PDM (pulse density modulation) output such as a MEMS microphone, or an input such as the decimator on a smartphone chip. In addition to standard audio measurements, APx provides variable DC voltage, variable sample rate, and PSR (power supply rejection) measurements for testing devices’ full operating parameters. Jitter capable.

SOFTWARE OPTIONS

APx500 software options provide measurements and functionality beyond the core set of capabilities standard for the APx555. 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 APx555. 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. Results include Rub & Buzz detection, essential Thiele-Small parameters, and impedance magnitude and phase. A proprietary modulated noise measurement is also provided to aid in detecting enclosure air leaks.

Electro-Acoustic R&D (SW-SPK-RD)
The SW-SPK-RD option delivers a complete suite of measurements and results tailored to the needs of designers and engineers developing electro-acoustic audio products. It includes key measurements and results such as complete Thiele-Small characterization; time-gated, quasi-anechoic Acoustic Response; Impedance analysis; plus the Loudspeaker Production Test measurements.

POLQA Perceptual Audio Test (SW-POLQA-2)
Perceptual audio measurement returns a subjective assessment of speech quality using the next-generation POLQA algorithm for wide-band speech devices or devices with acoustic coupling. (Successor to PESQ with support for HD Voice, 3G, 4G/LTE and VoIP technologies)

PESQ Perceptual Audio Test (SW-PESQ)
Widely-used, enhanced perceptual measurement for subjective assessment of speech quality on
low-bandwidth devices. (PESQ algorithm)
