Jitter Analysis Module Is Completely Digital

Claiming title as the marketÕs first fully digital optical-jitter measurement tool, the OTS9200 jitter analysis module employs the companyÕs patented digital phase analysis (DPA) technology. The module time stamps every edge of a SONET/SDH data stream and removes error sources and variables associated with PLL circuitry.Performing both jitter-generation and jitter-tolerance tests, the digital approach is also said to eliminate the need for range switching and PLL settling time. Pricing for the module starts at $64,500. For more details, call TEKTRONIX INC., Beaverton, OR. (800) 426-2200, code 1253.
