摘要
A novel method applies the down-conversion sampling technology to test a high-speed digital-to-analog conversion. In the method, a digital-to-analog conversion output signal of a high-speed digital-to-analog converter and a low-frequency sinusoidal carrier wave signal input to a comparator to obtain a low-speed pulse signal. Therefore, the variation of the pulse width of the low-speed pulse signal can be measured by a common logic analyzer to assess the nonlinearity error of the high-speed digital-to-analog converter.
