AN2686 Ethernet Compliance Testing for 10BASE-T, …
AN2686 . Ethernet Compliance Testing for 10 BASE-T, 100 BASE-TX, and 1000 BASE-T. Author: John MacKay Microchip Technology Inc. INTRODUCTION. The IEEE Ethernet Compliance Testing encompasses a wide range of tests that utilize different waveforms for the various device speeds: 10 BASE-T: Four waveforms (link pulse /idle, pseudo-random, all ones, and arbitrary waveform signal). 100 BASE-TX: Two waveforms (transmit scrambled idle and arbitrary waveform signal). 1000 BASE-T: Five waveforms (four test mode 1-4 waveforms and arbitrary waveform signal).
For link pulse testing with Twisted Pair Model, the DUT is connected to the DUT port for the 10BASE-T Parametric/Tem-plate Test with Twisted Pair Model, and the oscilloscope probe is attached to the test jumper after load selection. To configure the DUT for link pulse testing, refer to 10BASE-T Link Pulse Setting on any part for register settings.
