Some views of 1 Gbit/s (that's 1.25 GHz, or 800 ps per bit) synchronous ethernet bit-patterns.

4 GHz 'scope

We got this 4 GHz 'scope at work. 111 ps is roughly as expected for the rise-time of a fast edge. Signal from a leo bodnar pulse generator.

RA0SMS mini-whip

New RA0SMS mini-whip antenna on the roof. The old one lasted from 2017/02 to 2018/10.
