提出了一种采用Advantest 93000型自动测试设备,配合外挂高性能信号源SMA100A,对8位1.5GS/s超高速ADC进行动态参数测试的方案。该方案使用外挂信号源,提供采样时钟和模拟输入信号,解决了93000与外部信号源之间输入信号不同步,以及两者频率差异导致的采样不稳定问题,有效提升了93000测试超高速ADC动态参数的能力,可广泛应用于超高速ADC量产测试。
An advantest 93000 automatic test equipment is proposed to test the dynamic parameters of an 8-bit 1.5GS / s ultra-high speed ADC with a high performance external source SMA100A. The program uses a plug-in signal source to provide sampling clock and analog input signal, to solve the input signal between the 93000 and external signal source is not synchronized, and the difference between the two sampling instability caused by the problem, effectively enhance the 93000 test ultra-high speed ADC dynamic The ability of parameters, can be widely used in mass production of high-speed ADC test.
