멀티채널 분석을 필요로 하는 멀티채널 오디오
진정한 멀티채널 분석기는 단지 빠른 테스트뿐만 아니라 기기의 모든 입력과 출력 채널이 동시에 완벽히 동작해야 합니다.
오늘날, A/V 리시버, 디스크 플레이어, TV, PC 그리고 차량용 오디오 기기의 대부분은 2채널 이상이며, 서라운드 음향 분야에서 6채널(5.1)에서 16채널 또는 수많은 차량에서 그보다 많은 채널을 가지고 있습니다. 멀티채널 테스트를 위한 기존의 솔루션은 스위처를 사용한 2채널 분석기입니다.
두 가지 큰 문제가 있습니다. 첫째, 자동화 하였더라도, 채널간의 스위칭이 느립니다. 둘째, 동시에 단지 하나 또는 두 채널을 관찰하므로, 설계자와 제조사들은 채널간 상호작용을 자주 놓치게 됩니다. 위상 그리고 채널간 상호작용과 함께 최대 파워 출력 테스트를 하는 동안 눈에 띄지 않는 채널에서의 출력 세그 문제가 발생하고, 특히 각각의 모든 출력 채널들의 상호작용이 결합된 복잡함을 겪게 됩니다.

FEATURES:
Simultaneous Multichannel Audio Analysis
A true multichannel analyzer allows not just faster testing, but also a complete picture of the performance of all of a device’s input and output channels simultaneously.
Today, the majority of A/V receivers, disc players, TVs, PCs and automotive audio devices have more than two channels, from six channels (5.1) in surround sound applications to 16 or more channels in many cars. The conventional solution for testing multiple channels with a two channel analyzer has been to use switchers.
Such an approach has two major problems. First, even when automated, switching between channels is slow. Second, because only one or two channels are being observed at a time, designers and manufacturers are often blind to interactions between channels. Problems which may go unobserved include output sag in channels during full power output tests as well as phase and crosstalk interactions, particularly the combinatorial complexity of all the output channels interacting with each other.
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.
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.
