Waveforms of signal on a 10 Mbps Ethernet CAT5 cable (captured differentially on the RX+ and RX- wires):
For the info regarding how I managed to captured this waveform have a look at the usenet discussion here and the supporting info here.
Click on the image below to know how I forced my network card to operate in 10 Mbps mode only:
I have studied the signals on UTP cable known as the Pulse signal and a 4-wire cable used for data transmission.
So I asked.
1. Signal you measured it as a data or a Power in ethernet line? Because I got a same your signal from measure in osciloscope . I do not really understand.
2. How to measure it? I may be wrong osciloscope.
