10 Keysight E6960A User Guide and Method of Implementation
Introduction
Testing a 1000Base-T1 PHY's transmitter is accomplished through the use of
various test modes defined in the 1000Base-T1 specification. See “Reference
Documents” on page 44.
Keysight’s E6960A 1000Base-T1 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.
Using the Keysight E6960A 1000Base-T1 Compliance application software along
with an N5395C Ethernet Test Fixture greatly simplifies compliance testing. The
software automatically configures all of the required test equipment reducing the
overall test time.
The E6960A Software:
– Lets you select individual or multiple test to run.
