Anritsu unveils multi-channel BERT with up to 32 Gbps on four channels

Anritsu Co. has introduced 28G/32G multi-channel modules for its MP1800A Signal Quality Analyzer (SQA) BERT system. The new capabilities will aid equipment designers evaluate interconnect interfaces up to 32 Gbps. Among other applications, the new capabilities will play well in dual-polarization quadrature phase-shift keying (DP-QPSK) design applications.

The new modules provide the MP1800A with the ability to synchronize up to 12 pulse pattern generators (PPGs) in a single mainframe. The BERT system also will offer best-in-class intrinsic jitter and excellent input sensitivity, Anritsu asserts.

Applications include designs aimed at long-haul 100-Gbps DP-QPSK, where four synchronized PPGs with precise skew control are required. The system also will support measurement of jitter tolerance and cross-talk on high-speed backplanes and interconnects. It also can prove useful in designs targeting OTU-4, CEI-28G, 32G Fibre Channel, and Infiniband EDR.

The new modules the 28G/32G PPG modules (MU183020A, MU183021A) and 28G/32G Error Detector (ED) modules (MU183040A, MU183041A). The MU183020A 28G/32G PPG supports output for one or two channels, while the MU183021A supports simultaneous output for four channels. Each output channel supports data pattern synchronization and individual delay setting for high-accuracy crosstalk evaluation when transmitting multiple channels, Anritsu says. The PPG outputs 3.5-Vpp max. high-quality waveforms with an option for supporting direct driving of high-amplitude devices.

The MU183040A 28G/32G ED supports one or two measurement channels, while the MU183041A supports simultaneous input for four channels. The ED offers direct measurement of 50-mVpp data signals and offers input sensitivity that is 2X better than competitive products, Anritsu asserts.
