LUTON, U.K. -- In response to the concern among communications engineers that current next generation network analysis tools cannot guarantee accurate jitter evaluation, Anritsu has introduced the MP1590A-30, a high precision jitter analysis option for its MP1590A Network Performance Tester. The MP1590A-30 enables engineers to carry out highly accurate pattern jitter and random jitter testing, ensuring that the jitter measurements taken on SDH/SONET, OTU-1, and OTU-2 transmission equipment, during design and manufacturing, are traceable and reliable.

In order to achieve such high levels of measurement accuracy and repeatability, Anritsu produced a +/- 5mUI traceable reference source against which it could calibrate the testers. The MP1590A-30 delivers industry-best +/-20 mUIp-p accuracy in jitter measurement and also offers measurement repeatability of +/-5 mUIp-p, as well as exceptionally low intrinsic jitter of 50 mUIp-p. The MP1590A also demonstrates excellent low optical power dependency in the range from -7 dBm to -16 dBm and virtually no jitter in the ITU-T recommended range of -10 dBm to -12dBm.

The reference source uses a digital sampling oscilloscope to analyse the jitter of devices under test (DUTs). The MP1590A-30 verifies pattern dependent jitter by measuring the phase difference between the data falling/rising edges and the reference clock. Random jitter of the oscilloscope's trigger circuits is measured using SSB noise measuring equipment. An advanced DSP method is applied to the data to take account of the filter bandwidth and to synthesise the resulting jitter allowing the test time to be integrated into the result analysis.

Integration of the jitter analysis option is simple, due to the MP1590A's compact PCI card-based architecture. The unique design allows users to configure the MP1590A to conduct performance testing from 1.5 Mbps to 10.7 Gbps for electrical, 1310 nm optical, and 1550 nm optical signals. Previously, engineers could only perform these multi-bit rate measurements using a multiple-instrument test system. This flexible architecture is economical because users purchase testing capability only as they need it. Completely portable and based on standard Windows XP, the MP1590A is easy to operate, and as much as 60% smaller and 30% lighter than competitive instruments.
