Tektronix provides the most comprehensive solutions to serve the needs of engineers designing Thunderbolt silicon and host systems as well as those validating the physical-layer compliance of Thunderbolt devices to the Thunderbolt Interconnect Specification.

The Tektronix TBT-TX applications and selected Tektronix oscilloscopes provide one-button testing for Thunderbolt measurements as specified by the Thunderbolt specification. TBT-TX automates the measurements allowing engineers to perform the required tests efficiently and reliably right on their bench.

The DPO/DSA/MSO70000 Series oscilloscopes are designed to meet the challenges of the next generation of serial data standards such as Thunderbolt. These oscilloscopes provide the industry's leading vertical noise performance with the highest number of effective bits (ENOB) and flattest frequency response among oscilloscopes in their class.

TBT-TX – Thunderbolt Physical Layer Testing

With its fast data rate and multi-lane topology Thunderbolt will present a number of test and measurement challenges, including fixture effects and the need to isolate crosstalk. Coupling of energy from adjacent signaling lanes adds noise and jitter that can affect system interoperability. Effective debug requires jitter analysis tools that can properly separate and classify the jitter components of a signal, including those stemming from crosstalk.

Before the measurements are computed the test channel must be de-embedded. De-embed filters can be easily created using Serial Data Link Analysis software (SDLA) and then quickly entered into the TBT-TX measurement setup and saved for future use. In addition to jitter, TBT-TX also provides voltage, spread spectrum clocking (SSC), and other AC parametric measurements.

For compliance testing, TBT-TX automates the instrument setup as required by the Thunderbolt Specification including adequate time window for SSC analysis and PLL settings for jitter/eye analysis. The port microcontroller enables automated device automation through test pattern initiation. TBT-TX allows the user to automate test modes while integrating the required scripts or step through the test modes with manual device control. A test status window indicates current status of waveform acquisitions, signal analysis, and results documentation. The TBT-TX software can be run in Offline mode which allows the user to quickly recalculate test results using saved waveforms. A detailed test report provides color-coded Pass/Fail indications along with test margins. TBT-TX can be run in User-defined mode to debug test failures with custom settings and test limits.
