BroadR-Reach is an automotive Ethernet protocol that uses full duplex signaling along a single unshielded twisted pair (UTP) of wires.
Until now, most automotive Ethernet testing solutions required insertion of a hardware directional coupler to separate the bidirectional data streams. But such couplers can interfere with the normal function of the network and deliver misleading test results.
The software directional coupler featured in PicoScope 6.14.10 uses two non-intrusive differential voltage probing points a known distance apart and a velocity of propagation algorithm to separate the transmitted data waveforms in each direction. This enables non-invasive signal analysis and serial decoding.
