TDSET3 – Automated Ethernet Physical Layer
Compliance Testing
Ethernet compliance testing has some unique measurement challenges:
Generating the “disturbing ” signal requires tools to generate both pattern
data and noise to provide real-world noise for return loss measurements

in compliance with standards such as IEEE 802.3-2000 and ANSI
X3.263-1995. The portfolio of tests includes core PMA and MDI tests like
Template, Distortion, Return Loss, Jitter (including the proposed alternate
jitter method), and Common Mode Voltage.
Amplitude Domain Tests
The industry standards require th e signals to have amplitudes within
specified ranges to assure interoperabili

or p eak-to-peak amplitude, overshoot, common mode voltage, and
positive/negative pulse symmetry.
ty between devices. The amplitude
Return Loss Test
The return loss of the cabling system can also affect interoperability.
The standards define the minimum amount of attenuation the reflected
signal should have relative to the incident signal. The Return Loss test
measures the impedance, typically over the range of 100 ±15%. TDSET3
ingeniously performs the Return Loss test for 85, 100, and 115 (111 for
10BASE-T) impedances as prescribed by the standards, using the same
tools such as oscilloscopes and AWG used for other tests, enabling efficient
usage of resources.
Time Domain Tests
Timing parameters of the signals are also specified by the standards.
These tests include timing measurements such as rise time, fall time, and
difference or symmetry between rise and fall times.
Jitter Tests
Jitter tests quantify the timing variations of the edges of the signal, using
specified test patterns. These jitter measurements include the contributions
from duty cycle distortion and the baseline wander. Jitter is determined by
accumulating waveforms, measuring the widt h of the accumulated points
at the eye crossing, and the peak-to-peak is inferred from minimum and
ximum values in the tails of the histogram. For example, the figure above
ma
shows the jitter measurement on a 100BASE-TX signal.

Positive side AOI Template test of 100BASE-TX signal.
Template Tes ts
Template mask tests are often used to quickly verify that the transmitted
signal meets industry-standard requirements. These template masks
are defined so that signal distortions such as overshoot, jitter, incorrect
rise and fall times, etc., will cause the mask test to fail. An example of a
100BASE-TX template mask test is shown above.

10BASE-T and 100BASE-TX Decode
The DPO4ENET Ethernet Serial Application Module provides a higher-level,
combined view of the individual signals that make up the 10BASE-T or
100BASE-TX bus, making it easy to identify where packets begin and
end and identifying subpacket components such as preamble, SFD, MAC
addresses, data, FSC, errors, etc.
Are you wasting time manually decoding the waveform? Tired of having
to visually inspect the waveform to count clocks, determine if each bit is
a1ora0
, combine bits into byte s, and determine the hex value? Let the
MSO4000B or DPO4000B with a DPO4ENET Ethernet Serial Application
Module do it for you! Once you’ve set up a 10BASE-T o r 100BASE-TX bus,
the MSO4000B or DPO4000B Series will decode each packet on the bus,
and display the value in hex, binary, or ASCII in the bus waveform.
