PAM4 Measurements Through Lossy Channels – Why Oscilloscope CDR Emulation Matters
Date: Wednesday, October 28, 2026
Time: 11 AM Pacific | 2 PM Eastern
Duration: 60 minutes
Join Teledyne LeCroy as we describe how the shift to PAM4-based signaling schemes has introduced more complex figures of merit for transmitter characterization, which is requiring improved oscilloscope clock data recovery (CDR) emulation algorithm.
Topics to be covered in this webinar:
- Overview of industry standard methodologies for SNDR and Tx FFE measurements
- Signal impairment impact on methodology requirements
- Channel loss challenges during test environment measurement validation
- Impact of longer, higher-loss channels on conventional CDR emulation methods
- Comparison and contrast of existing SNDR and Tx FFE measurements to a new methodology
Who should attend? Engineers involved with designing and validating serial data links operating at speeds of 10 Gbaud or faster. This webinar is particularly relevant for applications involving very impaired (lossy) channels and PAM4 or higher-order modulation.
What will attendees learn? SNDR and Tx FFE measurement methodologies, impacts of CDR emulation algorithms.
