ABSTRACT:
Automatic test equipment (ATE) includes interleaved analog-to-digital (A2D) converters to produce digital signals, where the digital signals are used to produce an output signal, the output signal having spurs, a look-up table (LUT) to store correction values, where the correction values are for reducing the spurs in the output signal, and circuitry to apply the correction values to the output signal.
