ABSTRACT:
Automatic test equipment with programmable timing generators to generate digital signals and analog signals. The digital timing generator can be programmed to generate timing signals with a resolution finer than that of the master clock of the timing generator. Extremely fine resolution is achieved by specifying the numerator and denominator of a fractional portion of a period. A similar arrangement is used to allow fine frequency resolution for the analog timing generator. The fine resolution achievable with the timing generators allows the digital timing generator to be synchronized to the analog timing generator.
