In offering a complete toolbox for the busy test and measurement engineer, LeCroy devices provide the ultimate end-to-end solution for the design cycle. From physical layer measurement to expert protocol testing for the message layer, LeCroy’s unique hardware and software architecture ensure superior performance, excellent value, and the fastest time-to-market.

Software clock recovery eliminates trigger jitter

Measure data rates up to 3.5 Gb/s

Automatic mask alignment

Adjustable mask margins

Creation of user-defined masks

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.
