Interactive Protocol Table with Zoom and Pattern Search
Simply click on the packet of interest in the protocol table to create a zoom window of the waveform with color coded overlay showing the packet type, command type, and message details.
USB4 Type-C High Speed and Sideband Test Coupon
The TF-USB-C-HS probing coupon enables the industries only oscilloscope that triggers on USB4-SB signals and simultaneously captures high-speed data up to 20 Gb/s on an active link.
Use USB4bus standalone or with USB4‑SB TDMP Software for PHY Logic Layer Debug
Use TF-USC-C-HS (USB4 High-speed and sideband test Coupon Fixture), DH Series differential probes, USB4bus DME, and USB4-TDMP software to debug PHY link layer training failures on USB4 and Thunderbolt routers, re-timers, and active cables.
Eye Measurements
USB4 DME (Decode, Measure/Graph, and Eye Diagram) software provides eye diagram measurements by recovering the clock on decoded symbols. Used to evaluate high-speed signal quality during link training as the transmitter sends SLOS (Symbol Lock Ordered Sets) to the receiver during link training.
