Eye pattern of FC1063 optical signal
The SDM serial data mask package for Teledyne LeCroy WaveMaster series, WavePro 7000 series, WaveRunner 6000 and 6000A series and VBA adds eye pattern mask testing capability to the instrument. The user selects compliance masks from a comprehensive list of standards and the eye pattern is tested against this mask. User-defined masks are also possible by simply editing the included Microsoft™ Access2000™ data base file. The eye pattern is automatically aligned with the compliance mask.

The SDM package measures eye patterns by acquiring a long record of waveform data from the data stream under test. Once in the oscilloscope’s memory, a software algorithm computes a reference clock from the signal data which tracks the long-term variations in the data rate in the same way as a “golden” PLL does in hardware. The loop bandwidth of this software golden PLL is adjustable as a ratio of the measured bit rate. This ratio is variable from 1/20 to 1/10,000. Mask violations are counted and indicated by red circles in the display. The mask margins are adjustable both vertically and horizontally.

All of the data for the eye pattern are collected in a single acquisition thus completely eliminating any trigger jitter from the measurement.
