USB-PD TDMP

• The most comprehensive oscilloscope-based USB-PD solution
• Supports USB-PD 3.1 – EPR (Extended Power Range) and SPR (Standard Power Range)
• Comprehensive USB-PD Triggering Decode Power Delivery Objects (PDOs)
• Time correlate USB-PD protocol with V_BUS and I_LOAD measurements
• Measure VBUS@PS_RDY automatically
• BMC Eye Diagram and Physical Layer Measurements
• Time correlate USB-PD with AUX and USB4-SBU protocols
• Intuitive, color-coded decode overlays
• Interactive protocol table with zoom and pattern search
• Automated timing measurements
• Serial digital data extraction to an analog value (serial DAC) with waveform graphs
• Eye diagrams with failure location

USB-PD trigger types include preample, ordered set, control message, data messages, resets and errors. Providing a way to capture specific power delivery events. The same trigger types are also found in Teledyne LeCroy Voyager USB-PD compliance tester and Mercury sideband analyzers, which makes it easy to correlate between USB-PD protocol and electrical signaling between devices.

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand your 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 you just the right amount of information.

Turn the oscilloscope into a USB-PD 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.

The USB-PD Trigger, Decode, Measure/Graph and Physical Layer (TDMP) solution provides transparent color-coded decode overlays, protocol tables, and search capabilities, Measure/Graph capability with automated measurement and graphing tools for USB-PD and other USB Type-C technologies enabling the debug USB Type-C system issues by time correlating USB-PD messages along with other USB Type-C signals such as DP-AUX or USB4-SBU sidebands.

For system bring-up and debug, USB-PD TDMP options add a comprehensive suite of BMC Eye electrical conformance test measurement parameters– enabling USB-PD protocol issues to be tracked down to their root cause at the electrical level. Eye diagram and measurements for the bi-phase mark code (BMC) used for USB-PD are made on each packet and can be tested under USB-PD load conditions to insure conformance to the specification.
