10/100 Ethernet decoding software added to scopes

April 30, 2013 // By Julien Happich
Teledyne LeCroy has announced an Ethernet decode software option compatible with its wide range of oscilloscopes featuring bandwidths from 200 MHz to 65 GHz. With the software, users can decode 100BASE-T and 10BASE-T Ethernet signals to examine each frame within a given packet, assuring pre-compliance with IEEE standards.

The Ethernet decode software also aids in debugging issues that are not easily solved with a protocol analyser, such as interoperability issues, uncertain error causes, and physical-layer issues.

The Ethernet decode software processes physical-layer waveform captures to display a colour-coded overlay with easy-to-understand details on the stream's data-link layer. Decoded link-layer information expands or contracts as the user adjusts the oscilloscope’s time base or zooms in on the waveform, displaying more data with close-in views or less when looking at the big picture.

Powerful search capabilities allow users to search the acquired waveform in multiple ways. For example, users can search for frame types, source/destination addresses, data strings, and other attributes. A user can locate source or destination addresses from one frame and search the waveform for other packets with matching addresses. Locating errors is easy since the search tool provides a list of the most common error conditions such as missed start of frame, missed terminate frame and more. Decoded data is conveniently displayed in an interactive table. Clicking on any line in the table opens a zoomed view of that instance in the waveform.
