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
There are many individual amplitude, timing, return loss, and template tests required for each Ethernet variant:
The 10BASE-T standard specifies 22 tests per port plus fault tolerance and CMRR
The 100BASE-TX standard outlines 12 tests per port plus CMRR and more
The 1000BASE-T standard calls for 80 tests per port plus BER, CMRR, and more

Because of the large number of individual tests, compliance testing takes a lot of setup and measurement time, and makes repeatable measurement results difficult to achieve quickly
Performing return loss measurements can be expensive if using a vector network analyzer. Tektronix provides a patented, cost-effective method using an arbitrary waveform generator (AWG) and oscilloscope
85/100/115 Ω plots for the 100BASE-TX Return Loss measurement.
The TDSET3 provides automated compliance testing for 10, 100, and 1000BASE-T PHY verification, including:
Compliance and margin testing for accurate analysis and improved interoperability
Time- and frequency-domain measurements made with single analysis instrument
Jitter and timing measurements with and without filters
Amplitude, linearity, and droop testing for transmitter performance
Frequency domain measurements including return loss and power spectral density
User-defined mode enables flexible parameter control for characterization and margin analysis
Detailed test reports with margin and statistical information aid analysis
