  • Publication number: 20060285617
    Abstract: A method for synchronizing a plurality of sub-systems, comprising the steps of measuring a relationship between a divider associated with each of the plurality of sub-systems; and adjusting a phase of one or more of the dividers to a known relationship with one of the dividers. A command is issued synchronous to a divider associated with one of the plurality of sub-systems. The command is received at one of the sub-systems and is acted upon synchronous to a divider associated with the one of the sub-system receiving said command.

  • Publication number: 20060177018
    Abstract: A method and apparatus for digitizing a repetitive signal having a long pattern length is provided. The method comprises the steps of determining a clock period to be used when sampling the repetitive signal and determining a frame period of the repetitive signal. Thereafter, a sampling period is selected that is a relatively prime integer when compared with the clock period and frame period. The sampling period also comprises an integer number of time resolution periods, so that when sampling is performed in accordance with the sampling period, all time resolution periods are sampled at a same relative time position thereof.

  • Publication number: 20060176151
    Abstract: A method and apparatus for acquiring a signal employing a coherent timebase are provided. The method comprises the steps of defining a pattern length count of a repetitive pattern in a signal to be acquired, defining a number of samples per unit interval, and providing data strobes synchronous to a coherent timebase. An arbitrary one of the data strobes is designated as a timing for a potential trigger. A number of subsequent data strobes is counted in accordance with the pattern length count times the samples per unit interval and a portion of the signal corresponding to the pattern length count times the samples per unit interval is acquired beginning at a point in the signal defined by the designated arbitrary data strobe.
