How Does CrossSync PHY Connect a Protocol Analyzer and Oscilloscope?

CrossSync PHY enables waveforms from Teledyne LeCroy oscilloscopes to be viewed alongside protocol analyzer traces, with complete time-correlation of electrical and protocol information for easy and powerful validation and root-cause analysis.

CrossSync PHY capable PCI Express® interposers and USB 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

  • CrossSync PHY capable interposers and test coupon fixtures enable observation of both electrical and protocol behavior without disturbing the link
  • Sideband signals, reference clock and power rails are all easily accessible to oscilloscope probes
  • Optional high-bandwidth oscilloscope probing points for 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

CrossSync PHY Cross-layer Analysis Software

The CrossSync PHY software option for your Teledyne LeCroy oscilloscope enables precise, intuitive navigation between time-correlated protocol analyzer and oscillscope traces.

  • 1CrossSync PHY navigation bar makes clear the timing relationship between linked protocol analyzer and oscilloscope captures.
  • 2One or many oscilloscope acquisition segments are represented in the navigation bar.
  • 3Protocol analyzer trace represented in the navigation bar.
  • 4Common trigger point ensures precise timing alignment between protocol trace, oscilloscope acquisitions, and navigation bar view.
  • 5Oscilloscope timebase and protocol analyzer acquisition window remain synchronized while navigating through the combined acquisition, for total confidence in timing behavior.
  • 6Selecting a packet on the protocol trace enables zoom traces on the oscilloscope to the same time window, enabling sub-packet-level measurement precision
