According to one embodiment of the present invention, a system (100) for measuring overall jitter is disclosed that includes a data converter (102) that measures a signal to generate a first measurement set (212) and a second measurement set (214), which are used to compute overall jitter. According to one embodiment of the present invention, a method for measuring overall jitter is disclosed. The data converter (102) generates the first measurement set (212) and the second measurement set (214) by measuring the signal. The overall jitter is computed using the measurement sets (212 and 214). According to one embodiment of the present invention, a system (400) for measuring internal jitter is disclosed that includes a splitter (404) that splits a signal into an input signal (406) and a clock signal (410). The data converter (102) measures the input signal (406) to generate a first data set and a second data set, which are used to compute the internal jitter of the data converter (102). According to one embodiment of the present invention, a method for measuring internal jitter is disclosed. A signal is split into an input signal (406) and a clock signal (410). The data converter (102) measures the input signal to generate the first data set (508) and the second data set (512). The internal jitter is computed using the first data set (508) and the second data set (512). The external jitter is computed from the overall and internal jitter. The signal-to-noise ratio of the data converter (102) is computed from the external jitter.
