32-channel synchronisation upgrades signal quality analyser
Anritsu has upgraded its MP1800A Signal Quality Analyser by adding a 32-channel synchronisation function for 32 Gbit/s data signals. The new function enables the configuration of highly accurate test systems for the measurement of the next generation of ultra-fast communications technologies operating at speeds of 400 Gbit/s and 1 Tbit/s.
When equipped with the upgrade, up to four MP1800A mainframe units, each with an 8-channel 32 Gbit/s pulse pattern generator (PPG) may be synchronised. They may then be used to measure the operation of new communications technologies, such as Quad DP-16QAM and Dual DP-64QAM, which exploit phase modulation methods as a means of expanding core network capacity while limiting the bit rate per channel.
Installing either four two-channel or two four-channel 32 Gbit/s PPG boards in four connected MP1800A mainframes provides 32 channels of 32 Gbit/s, offering a transfer capacity of 1 Tbit/s. With a high-accuracy function for adjusting the phase in 2-mUI (milli-Unit Interval) steps, the 32 Gbit/s PPG installed in the analyser enables easy configuration of a test system that offers accurate phase control.
Additionally, high repeatability can be achieved, because the PPG’s 32 Gbit/s data-signal bit pattern itself can be generated at any timing interval. The upgrade is expected to help researchers, equipment manufacturers and network operators move forward more quickly with the implementation of next-generation, ultra-fast communications network technology.
