Keysight E6961A User Guide and Method of Implementation
Introduction
BroadR-Reach specifications (see
the use of various test modes for testing compliance with the BroadR-Reach
Physical Layer (PHY) transmitter. BroadR-Reach was developed by Broadcom
Corporation specifically for automotive applications. OPEN (One Pair EtherNet)
Alliance standardized the technology and established the standard. 100 Mbit/s
Ethernet for automotive applications was standardized as IEEE 802.3bw with the
terminology 100 Base-T1.
Keysight’s N6467B 100BaseT1-TX Compliance Application Software (provided as
a software option to the E6961A Automotive Ethernet Solution) provides five test
modes for the testing and validating the transmitter waveform, transmitter
distortion, transmitted jitter, and transmitter droop. The test modes change only
the data symbols provided to the transmitter circuitry and do not alter the
electrical and jitter characteristics of the transmitter and receiver from those of
normal operation.
