Virtual Eval is a web application to assist designers in product evaluation of ADCs and DACs. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, frequency response plots, and more.
This tool illustrates the aliasing effects of an input signal and its harmonics when digitized by an ADC. The user can select single tone or a modulated carrier input signal and can observe aliasing in up to 10 Nyquist zones.
