Anritsu Corporation has revealed a number of upgrades to its MP1800A signal quality analyser with a number of new functions enabling 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 MP1800A 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.
By adding this new 32-channel 32 Gbit/s PPG synchronisation upgrade to its MP1800A test solution, Anritsu is expecting to help researchers, equipment manufacturers and network operators to move forward more quickly with the implementation of next-generation, ultra-fast communications network technology.
