Introduction to LeCroy’s Ethernet Package As the Ethernet connection evolved over the years from one stage to another, it kept some characteristics unchanged, such as frame formats. Other parts, however, kept changing constantly. Among these are the Physical Layer specifications. 10Base-T, for example, uses 2 level Manchester encoding; 100Base-T uses 3 level MLT-3 signaling, while Gigabit (1000Base-T) uses 4D-PAM5, based on 5 level signals. Therefore, while the evolution seemed natural and easily implemented by the network manager, hardware designers and manufacturers alike found it more complicated. Actually, much more complicated, as in the case of 1000Base-T LeCroy's Ethernet Package bridges the gap between the different testing methods for 100 and 1000 Mbps. It is based on a Software package that can be installed on DSOs with 1 GHz bandwidth or higher. The result is a user-friendly solution that dramatically reduces testing times and simplifies the testing process. Tests and calculations are performed inside the DSO, bypassing the need for external programs (such as MATLAB) and making the use of analog filters unnecessary. You can select between 100Base-TX and 1000Base-T. Each standard has a specific array of tests to be performed. After selecting a test, waveforms are displayed on the DSO grid(s) while the measurement results are listed below. Some measurements include statistics. The package can be easily customized, by adding new masks (PolyMasks). The DSO can perform other tasks in parallel, and unused channels may be used for more testing.
