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 Advantest 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.


  • Excellent waveform quality
  • Generation of SDH/SONET frame patterns (mixed patterns)
    which are close to actual data
  • 8 M-bit memory, 31 stages for PRBS
  • Multi-channel output : 2 data channels, 3 clock channels, and
    sub-rate channels
  • Cross point variable for output waveform
  • Burst signal output
  • 3 Vp-p outputs, effective for EA modulators, etc. (option)
