World's smallest jitter analyser that measures jitter characteristics at 2,5 Gbps and 10 Gbps

Anritsu has released the MP1580A, claimed to be the world's smallest jitter analyser that provides highly accurate measurements of jitter characteristics at 2,5 Gbps and 10 Gbps. Additionally, the MP1580A is the only analyser that can generate variable types of TDEV (Time Deviation) masks at 10 Gbps when conducting wander measurements. The combination of such unique features and measurement capabilities makes the MP1580A an excellent tool during the R&D, manufacturing, installation, and maintenance of SONET/SDH systems and networks, according to the company.
Measuring only 320 x100 x 350 mm, the MP1580A is designed for use with Anritsu's MP1570A/A1 portable SONET/SDH/ATM analyser. The MP1580A fully conforms to the Bellcore GR-1377 and exceeds the latest ITU-T 0.172 standards for measuring instruments. It offers jitter bandwidth up to 80 MHz for jitter generation and measurement, as well as up to 4000 Ulp-p maximum jitter modulation amplitude for testing at 10 Gbps. According to the company no other instrument on the market can measure both 2,5 Gbps and 10 Gbps within the same configuration.
Six high-speed jitter and wander measurements can be made automatically with the MP1580A. The analyser can measure jitter tolerance, jitter sweep, jitter transfer, frequency sweep, wander sweep, and wander. A number of other jitter and wander measurements can also be made with the MP1580A.
Anritsu has written wander application software that allows the MP1580A to perform wander measurements at 2,5 Gbps and 10 Gbps. With the software, realtime MTIE and TDEV measurements conforming to G.813 can be made via an external PC. Other wander measurements, including holdover, wander tolerance and wander transfer, can also be made with the MP1580A when the software is installed.
While the MP1580A is an effective single instrument solution for conducting clock jitter measurements, it is intended to be combined with Anritsu's MP1570A/A1 for accurate analysis of jitter tolerance, jitter transfer characteristics, and jitter generation. In this configuration, both 2,5 Gbps and 10 Gbps jitter measurements can be made on electrical and optical signals. Because both the MP1580A and MP1570A/A1 have identical key layout and response, such complex jitter measurements can be made simply and automatically.
