D90103CKC IEEE 802.3ck Measurement and Conformance Application Software

Measurement and Conformance Application Software

Characterize IEEE 100/200/400 Gb/s (53.125GBaud PAM4) Electrical TX Designs using Infiniium UXR-Series Oscilloscopes,

Introduction

Several industry and IEEE standards Associations have defined an electrical specification for 100Gb/s over one copper lane on the Physical Medium Attachment (PMA) Sublayer & Physical layer.  As an example, chip-to-chip or chip-to-module interface of 100/200/400 Gb/s designs, or backplane (KR) or shielded balanced copper cabling (CR) defined by IEEE P802.3ck.

The Keysight D90103CKC IEEE P802.3ck software is a measurement application for the Infiniium UXR-Series oscilloscopes designed to save you time and money performing the adaptive reference equalizers and 53Gbd PAM4 transmitter (TX) test measurements in an easy to use, test solution.

Transform Complexity into Simplicity

The D90103CKC is an easy-to-use TX test application that:

• Saves time in understanding details of unique standards measurements

• Offers site to site consistency in uniform measurement results

• Reduces the time it takes to characterize your 53Gbd PAM4 design from hours to minutes 

• Helps debug your device using custom configurations 

• Allows you to quickly generate HTML reports that summarize the performance of your device

Select Industry-leading Hardware

D90103CKC application is specifically designed to leverage the hardware-based equalization and filter acceleration of the Infiniium UXR-Series of real-time oscilloscopes.  The Infiniium UXR-Series is highly accurate on timing/jitter related measurements and supports an exceptionally precise PLL implementation achieved with advance signal processing.  

Certain IEEE 100G C2M measurements require an input referred noise floor of 1.28mV RMS which depending on the measurement signal level, can be exceeded on the UXR.  Due to the noise sensitivity of these operations, users should be cognitive of the relative benefits of a N1000A DCA-X sampling oscilloscope compared to the Infiniium UXR-Series oscilloscope in interpreting the results and accuracy of these automated IEEE C2M measurements.

The family of 53.125GBaud measurements found in 100GAUI, C2M, C2C, KR-n and CR-n require a 4’th order Bessel-Thomson channel response (4BTR) at 40GHz, tracked out to -9dB.   This 4BTR tracking generally requires a UXR with 59GHz of bandwidth to accommodate.   Lower bandwidth Infiniium UXRSeries oscilloscopes can be used with a higher measurement error consideration.   Higher bandwidth Infiniium UXR-Series oscilloscopes will be digital filter constrained to this spec mandated 40GHz 4BTR, rolling off to -9dB on a Bessel-Thomson channel response at 59GHz.
