Abstract: An apparatus and method for processing a data signal is provided. An acquisition unit of a test instrument acquires a data signal for a predetermined time. The data signal is stored in a memory of the test instrument and a clock recovery unit recovers a clock signal from the stored data signal. The stored data signal is sliced by a processor into a plurality of data segments of a predetermined length in accordance with the recovered clock signal.

Abstract: A method and apparatus for determining a bit error rate. The method comprises the steps of acquiring a data signal by an acquisition unit of a test instrument for a predetermined period of time, and storing the data signal in a memory of the test instrument. A clock signal is recovered from the stored data signal, and in accordance therewith, the stored data signal is sliced into a plurality of data segments of a predetermined length. Each of said data segments is synchronized to a frame or predetermined pattern to determine a bit error rate thereof.

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.
