品牌：QuantAsylum
类别：音频分析仪
型号：QA403

公司介绍：
     自2010年起，QuantAsylum一直致力于开发并向嵌入式硬件与软件开发者提供独特产品。 
QuantAsylum一直为世界各地的公司提供音频测试和测量。随着每次迭代，分析器的能力和可编程性都在不断增长。 
经济实惠且功能强大的音频分析。

产品简述：
QuantAsylum QA403是我们的第四代音频分析，无论您是在家工作几天还是建立生产线，QA403都能提供您所需的性能，
并留有余量，以测试当今开发的大多数产品。使用附带的软件或您编写的软件，它可以快速完成。
我们的一些客户已经购买了50多台分析仪，用于研发和制造。这是一个经过验证的平台，其功能会随着时间的推移而不断发展。 
    QA403通过以下方式扩展了QA402的功能，改善了噪声和失真性能，此外，频带边缘的响应更平坦。 
    QA403的紧凑型尺寸（177W x 44H x 97D mm和450g）意味着你可以把它带到任何地方。  

产品参数：

OS Supported：Windows 10. Other versions of Windows may work but are not routinely tested. 
USB Connector: USB Type B
USB Current:800 to 900 mA or more depending on connected loads. This is readily provided 
                     by a powered hub but might be too much for some laptops. Additionally, 
Isolation:The QA403 was tested during design to offer >10Gohm of isolation between 
                   Audio Common (BNC Shell) and USB ground (USB shell) @ 1 kV test voltage. 
Sample Rates:48, 96 and 192k SPS for ADC and DAC. ADC and DAC always have the same sample rate. 
Dimensions: 177W x 44H x 97D 
Weight: 435 grams 
Case Material: Powder-coating Aluminum (2mm thick front panel, 1.6mm thick top/bottom) 
Electrical ADC (See Attached Performance Plots) 
Inputs: Differential, BNC x 2 for LEFT and BNC x 2 for RIGHT 
Input Z: 100KΩ AC-coupled unbalanced (single-ended) 
             200KΩ AC-coupled balanced 
Input Coupling: AC, Fc < 1 Hz 
Input Max DC: ±40V balanced or single-ended. |AC + DC| must not exceed 56VPK on any input 
Input Full Scale (Atten OFF): +18 dBV = 8VRMS balanced or single-ended 
Input Full Scale (Atten ON): +42 dBV, but input is clipped by software to +32 dBV = 40VRMS.
