The jitter yield measurement equipment and the method of making the efficient measurement and precise appraisal of jitter yield quality possible

摘要

The control section as in the degree which controls the combination of frequency of the clock pulse and frequency of the modulating signal variably by controlling the clock pulse generator and the modulating signal generator, amplitude of the aforementioned modulating signal is controlled variably, being based with on the decision result of error of the data signal of the specified pattern which is output from suffering measurement ones due to the aforementioned decision section, and the information of amplitude of the aforementioned modulating signal calculates the value which shows the jitter yield of aforementioned suffering measurement ones. Receiving with the frequency of the aforementioned clock pulse which is controlled by the aforementioned control section, the frequency of the aforementioned modulating signal and each information of amplitude of the aforementioned modulating signal and the value which shows the aforementioned jitter yield, it indicates the indicatory department, in simultaneously on the picture of the indicator the jitter yield quality of aforementioned suffering measurement ones as two parameters of frequency of the aforementioned clock pulse and frequency of the aforementioned modulating signal.
