This is an Advantest D3186 Pulse Pattern Generator & D3286 Error Detector. The system has options 70 (Mixed Patterns Generation).

To accommodate transmission of large capacity information in the coming multimedia generation, ultra high speed digital telecommunications networks are being constructed. For evaluation and analysis of O/E and E/O modules and ultra high speed logic devices used for multiplexers and repeaters for telecommunications systems, a signal source with high speed and high quality is necessary. The D3186 Pulse Pattern Generator/D3286 Error Detector offers excellent waveforms with high speed and high quality and diverse error detecting functions in an operating frequency range from 150 Mbps to 12.5 Gbps. In addition, with the 8 M-bit large capacity memory and ADVANTEST's unique frame pattern generation function, the D3186/D3286 is a new generation of error performance test system which is compatible with STM-1 (155.52 Mbps) to STM-64 (9.95 Gbps) in SDH/SONET.

FEATURES: The system covers a broad frequency range of 150 Mbps to 12.5 Gbps with 1 kHz setting resolution, providing 9 types of pseudorandom patterns, programmable word patterns and frame patterns. Complementary data outputs in binary code NRZ with a 10 mV setting resolution, minimal jitter and lowest rise and fall time waveform characteristics with phase delay settings of 1 ps step resolution are state-of-the-art features. The clock source is either internal with a 0.15 ...12.5 GHz or a 2 ... 12.5 GHz generator optionally or
