TF-ENET-B is required to test all 3 standards (10/100/1000Base-T). All signal connections to the digital oscilloscope use SMA cables in order to avoid any influence from additional circuits such as probes. The test fixture is designed to include –3 dB power splitter for disturbing signal tests in the 1000Base-T. The kit includes 50 ohm terminators (6), 6" Ethernet cable (1) to connect to the DUT, SMA cables (2), and BNC to SMA adapters (2).
