Latest Ethernet Testing Advances To Be Revealed at PCB Live

Pico Technology has released a new BroadR-Reach decoder/analyzer package that simplifies Automotive Ethernet integration testing and debugging. The package includes a novel non-intrusive Software Directional Coupler to separate up- and downstream traffic on full-duplex communication lines, and electronics designers will be able to discuss this latest advance, and other offerings in the Pico Technology portfolio, at the forthcoming PCB Live event on March 12th.

BroadR-Reach allows multiple in-vehicle systems to simultaneously access information over single unshielded twisted-pair cables. The technology delivers relatively high-speed data, 100 Mbps, with low connectivity costs and cabling weight.

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 normal functioning of the network and deliver misleading test results. The PicoScope Software Directional Coupler utilizes two non-intrusive differential voltage probing points a known distance apart, together with the known velocity of propagation in standard RG58 or Cat5 cable, to separate the transmitted data waveforms in each direction.
