Solutions for Emerging OIF-CEI and IEEE PAM4 Standards
As network bandwidth needs continue to rise, PAM4 (4 level pulse amplitude modulation) is emerging as a key enabler to meet this need. With 2 bits per symbol, 4 symbol levels, and 3 eye diagrams per UI, PAM4 presents many new measurement and testing challenges.
Tektronix, at the leading edge of signal fidelity, works in collaboration with datacom engineers and standards organizations to help pioneer the measurement techniques needed to perform PAM4 Tx and Rx characterization up to 112Gbps/56Gbaud for emerging OIF-CEI and IEEE PAM4 standards.
Enabling PAM4 for Emerging Requirements in Data Communications
This webinar presents measurement techniques for PAM4 Data Communications and is useful for engineers involved in designing and developing 28G, 56G or 100G components, modules and systems. Find out more about:
- The difference between PAM and NRZ
- The challenges with PAM signaling
- Recommended methodologies for validating PAM signals
- Transmitter and receiver test tools and techniques

|PAM4 in 400G/200G/100G/50G Networking Technology|
|Overcoming SNDR Measurement Challenges in 100G, 400G Datacom Testing|
With important changes occurring in transmitter characterization and measurement methods for 100G and 400G standards (both IEEE and OIF-CEI) it is vital to learn more about SNDR and its advantages, key instrument considerations to account for, and how acquisition bandwidth influences SNDR noise parameters and more.
|PAM4 Electrical Webinar|
This presentation will review PAM4 measurement methodologies and expand on emerging needs related to FFE reference equalization, clock recovery challenges, BER measurement needs as well as SNDR as it relates to multi-level signaling.
|Practical 400G PAM4 Test Methods - Optical and Electrical Measurement|
The accelerated development of 400G Ethernet technology is driving new requirements through the test community as it relates to measuring PAM4 signals for optical and electrical systems. This presentation will review both of these two very different technology fronts and discuss practical elements of physical layer PAM4 testing ranging from 50mm based CEI-XSR specs to 10Km 400GBASE-LR8.
