TF-USB-C Test Coupon Fixtures eliminate the complexity of cross-probing the same interface for capture by both the protocol analyzer and oscilloscope.

Validate and debug active link operation

  • TF-USB-C-HS Test Coupon Fixtures enable observation of both electrical and protocol behavior without disturbing the link
  • USB Type-C Sideband signals accessible using passive or active probes
  • High-bandwidth oscilloscope probing points for USB data lanes

Quickly resolve interoperability issues by capturing the entire protocol stack

  • Trigger protocol analyzer and oscilloscope captures on the same high-level event
  • Easily measure timing relationships between protocol and electrical domains
  • Faster root-cause analysis means fewer costly finger-pointing exercises

Analyze link training with integrated physical and protocol views

  • Observe electrical-level results of protocol-level commands
  • Combined navigation means always knowing which protocol and electrical behaviors happen at the same time
  • No single instrument can deliver this level of cross-layer insight into link training

Unmatched PHY-logic
and Sideband Debug

Link training and sideband negotiation failures account for many compliance and interoperability failures found on USB Type-C connected devices. These failures can be quickly identified as either physical or link layer issues by using Teledyne LeCroy's Physical Layer Logical Sub-Block and Sideband debug solutions that include:

  • Oscilloscope probing access to all signals at the USB Type-C connector (TP2 or TP3)
  • USB4 PHY-Logic and Active Re‑Timer measurements
  • USB4, USB 3.2, USB 2.0, Power Delivery, and Alt Mode analysis
USB4 PHY-logic debug with  M4X Exerciser/Analyzer and SDA 8-ZiB oscilloscope
USB Type-C USB4 high-speed and sideband debug/test coupon fixtures

Probe all Signals at the USB Type-C Connector

USB Type-C Test Coupons Fixtures provide probing access to all signals at connector test points (TP2 or TP3) without impacting the performance of the system under test.
