产生音频白噪声. 传统的噪声发生器实际上只产生白噪声和粉红噪声,它需要与加权滤波器、功率放大器和真正的均方根电压表(共4路电路)相结合,才能用于扬声器的测试.***1 C由上述4种电路组成,可产生粉红噪声、白噪声和其它3种符合上述国家标准的加权噪声. 如果需要特殊的噪声频谱,用户可以在噪声信号输出和功率放大器输入端子之间插入自制的加权滤波器. 用法: 1.扬声器、耳机、扬声器系统和交叉系统的连续负载测试. 2.根据连续载荷试验的结果,确定了待测样本的额定输入功率. 3.将噪声信号注入扬声器,以测量扬声器的声压灵敏度(dB值)。 4.结合音频频谱分析仪测量扬声器的频率响应曲线. 注: ***1 B型是旧型号,已经停止生产,它现在正在被取代****1 C型.***1 C型和***1 B型之间唯一的区别是****1 B型使用旧的EIA **6 A标准加权过滤器(EIA***6 A已被废除);而***1 C使用符合新要求的EIA **6 B标准的加权过滤器.太阳光还提供:***1 FT*1型噪声过滤器,符合,IEC*****1标准.(它必须与型号****1 B或型号****1 C结合使用)。 |
Model
- ***1FT - 1 (1) ***1FT*1 is the weighting filter made in accordance to IEC*******1 requirement, it must linked with either Model****1C or ***1B made by Sunlight Electronics Laboratory, to enable it to generate weighting noise filter that complied with IEC*******1 requirement , for undergoing the life testing of the loudspeaker and by defining the rated power of the loudspeaker. (2) When using please take note that: The signal adopts the Pink Noise, and not other signal of noise sources. (3) Furthermore, the noise generated from this weighting filter also complies with the filter noise required by the JIS C***2 . |
