Description

The M8091CKPA receiver test application is designed to assist and simplify the testing of electrical interfaces inputs according to the IEEE 802.3ck, draft 1.2 chip-to-chip (C2C) and chip-to-module (C2M) recommendation using a Keysight M8040A 64Gbaud Higher Performance BERT and a Keysight Digital Communication Analyzer (DCA) Oscilloscope. Remote instrument control means all required calibration routines and compliance testing are performed automatically with reduced user interaction.

Interoperability of digital interfaces, following IEEE 802.3ck is expressed in terms of Channel Operating Margin (COM) for C2C interface and using the stressed eye method for C2M. COM is calculated out of the channel 4-ports S-parameters and of the noise and equalization functionality of the considered transmitter and receiver. In the stressed eye method, the receiver is tested with the worst possible signal allowed by the standard.

Results of the individual calibration steps and tests are presented in tabular form as well as graphical form where appropriate, which can be stored in projects and recalled at a later point in time. HTML reports are also possible.
