Colleagues-
Thanks George for the information. Hello to all, I review the last days for another project the market for field testers. The best handheld cable testers I found in the market can measure up to 2GHz or 2,5GHz bandwidth. Some of the HF experts in our lab and the market pointed out only below 3 to 3,5GHz bandwidth such handheld tester are possible and economical feasible. For higher frequencies the high-end lab equipment (Vector Network Analyzer) is needed. Following the discussion about the bandwidth for Multi-Gig Ethernet we should have this point in mind. All cable harnessing’s must be tested from the harnessing production before the wire harness installed into the car. And the price for the test equipment and the testing cost are also important for the car industry. Also for maintenance in the field test equipment is needed. From this point of view my understanding is we should use a bandwidth below 3 to 3,5GHz.
Matthias point is well made. Please remember that harnesses will have to be tested in automotive body shops and repair shops around the world including lesser developed countries. The automotive market is a world-wide market. Maintainability of high speed networks will be a major factor and challenge to their adoption.
