Hello,
we want to decode a Ethernet 100BASE-TX signal with the Picoscope 544D.
I connected Tx+ and Tx- against ground on two Channels. In order to Decode I build the Mathematical Channel A-B and attach Serial Decoding to it.
I tried different sampling rates and different voltage Levels, but I can't get the decoder working. Sometimes the sample rate switches automatically back to 10MS.
Screenshot in the attachment.
What am I doing wrong, what else can I try?

Use the Views->ViewProperties to open a panel on the right hand side that shows exactly how the scope has been setup.
If you turn off the decoding and the math channel, collect a single buffer of data at the best resolution possible, and with the scope stopped enable the math channel and the decoder do you get data ?
If this doesn't work then email support@picotech.com to discuss this in more detail.
