概要（Overview）

D3186 is a high-performance pulse pattern generator to generate 7 types of pseudo-random (PRBS) patterns from 2(7)-1 to 2(31) -1, programmable (WORD) patterns up to SM 2(23) bits, or frame patterns of SDH or SONET structure at very high speed from 150 Mb/s to 12 Gb/s. Moreover, a system, which is used to evaluate the bit error rate of super-high speed optical communication devices and compound semiconductors, can be structured by combining D3186 with the D3286 error detector.
