The MP1777A is a measurement solution for jitter evaluation. It supports both the STM-16/32/64 and OC-48/96/192 bit rates. In addition to supporting the bit rates of 2488.32, 4976.64, and 9953.28 MHz four additional bit rates used in submarine cable systems can be added as options. The MP1777A can evaluate jitter characteristics, including jitter tolerance, jitter transfer and output jitter, which are parameters most commonly used to evaluate digital lines.
