The KJM6775 is an improved version of the KJM6765 and the KJM6755A which are widely used in the market. KIKUSUI proudly presents this cutting edge model developed to support the next generation media.
The KJM6775 is capable of 3 types of jitter measurement: RF to CLOCK jitter, Bi-Phase jitter, and wobble-jitter measurement. It provides a maximum frequency of 220MHz and high-speed processing with a maximum of 74MSPS for RF to CLOCK jitter measurement. This instrument is suitable for jitter measurement of high-speed optical drives and next generation discs. The PLL clock regeneration circuit supports the CD standard speed (as specified in the Compact Disc Reference Measuring Methods Specification Guideline Ver.1.0 May 1999), 2x, 4x, 8x speeds, as well as the DVD-ROM standard speed (as specified in the DVD Specifications for Read-Only Disc Ver.1.0 Aug. 1996), and 2x speed. Since the equalizer is equipped with an equalizer circuit for DVD-ROM standard speed, it is possible to perform measurements conforming to the DVD Book standard on an RF signal input from an optical pickup.
The instrument applies a method for jitter detection where the input data is accumulated as a histogram, then digitally processed all at once, which allows measurements on a single-shot signal or only on part of a disc by combining the three functions of arming, arming delay and inhibit.
