The Teledyne LeCroy HDO4K-SMBUS TD SMBus Trigger Decode (TD) solution provides high performance triggers and transparent color-coded decode overlays, protocol tables, and search capabilities.

Capability is provided to permit triggering on any standard SMBus command protocol as well as user-defined command codes, with full capability to define specific data values or ranges of data values.

The trigger permits a conditional setup for the DATA condition. This is especially useful in situations where abnormal events should be monitored.

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show just the right amount of information.

Turn the oscilloscope into a protocol analyzer with a tabular display of decoded information. Customize the table to show only the data of interest and touch a message in the table to automatically zoom to it and display it on the screen. Export the table for offline analysis. Up to four different decoded signals of any type may be simultaneously displayed in the table.
