USB 3.0 bus

The USB 3.0 decode option for Teledyne LeCroy oscilloscopes provides link layer decode information annotated on the USB 3.0 physical layer waveform. This provides the ability to view protocol traffic on the oscilloscope and verify that the link is alive and transmitting properly. It also aids in debugging problems that are not solely analog or digital in nature, such as interoperability issues, uncertain error causes, and physical layer issues not evident with a Protocol Analyzer.

Protocol Awareness in Your Physical Layer Tool

Oscilloscopes are the preferred tool for the hardware engineer, but have been of limited utility in interpreting serial data protocols. Protocol Analyzers are powerful, but don't show physical layer waveforms. The USB 3.0 decode option for Teledyne LeCroy oscilloscopes provides link layer decode information annotated on the USB 3.0 physical layer waveform. This provides the ability to view protocol traffic on the oscilloscope and verify that the link is alive and transmitting properly. It also aids in debugging problems that are not solely analog or digital in nature, such as interoperability issues, uncertain error causes, and physical layer issues not evident with a Protocol Analyzer.

Intuitive Decode Annotation

Various sections of the protocol are color-coded to make it easy to understand. Decode annotation information condenses or expands depending on the time base/zoom ratio setting. Additionally, 8b/10b decode annotation (a separate option) may also be applied for symbol level debugging. The decode operation is fast—even with long acquisitions.

Convenient Table Display and Search

Long oscilloscope acquisition memory provides long capture times of USB 3.0 transmissions. Decoded information is conveniently shown in a table format, and specific frame types may be searched for. In addition, table data may be exported as a .csv file.

Support on Multiple Oscilloscope Platforms

To support the range of users, from USB 3.0, the option is available on a wide range of oscilloscope models with real-time bandwidths from 2.5 GHz to 30 GHz.
