Datasheet TDSET3 – Automated Ethernet physical layer compliance testing Wide range of tests 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...

Ethernet 10/100/1000BASE-T Application Software — TDSET3 • SR-ENET • DPO4ENET Jitter tests Test fixtures 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 width of the accumulated points at the eye crossing, and the peak-to-peak is inferred from minimum and maximum values in the tails of the histogram. For example, the preceding figure shows the jitter measurement on a...

In the past, users had to manually scroll through the waveform counting and converting bits and looking for what caused the event. With the SR-ENET application installed, you can enable the oscilloscope to automatically search through the acquired...
