用于录音机和录像机质量保证的全自动测试系统TS6010(图1),两年前由R/S公司首创,在其测量速度方面现在已经最佳化(测量参数见表1)。该系统的模块组件现在能够进行特别迅速的固定频率失真测量以及通用失真测量。由于采用了衰减量为50dB的专用带阻滤波器,失真测量是以两个快速电平测量(0.8秒)为基础的。失真=谐波/基波如果测量了V_总(无带阻滤波器时的电平)和V_滤(有带阻滤波器时的电平),那么系统按如下方式确定失真度:
The TS6010 (Figure 1), a fully automatic test system for quality assurance of voice recorders and recorders, was first launched by R / S two years ago and is now optimized for its measurement speed (see Table 1 for measurement parameters). The system’s module components are now able to perform particularly fast fixed-frequency distortion measurements as well as general-purpose distortion measurements. Due to the use of a dedicated band-stop filter with a 50 dB attenuation, the distortion measurement is based on two fast level measurements (0.8 seconds). Distortion = Harmonic / Fundamental If the V_ total (level with no band stop filter) and the V_filter (with band stop filter) are measured, the system determines the distortion as follows:
