Demonstration of latest updates to my software for the LiteVNA and V2Plus4 supporting unlimited memory storage. For more details, refer to the following link on EEVBLOG: Intel paper: 1000BASE-T/100BASE-TX/10BASE-T Physical Layer Compliance Tests Manual 100BASE_TX 10BASE_T Physical Layer Compliance Tests Section: 1000BASE-T MDI Return Loss The BALUN uses a Mini-Circuits TC1-1-13M. The paper shows a start frequency of 1MHz where this transformer is spec'ed for - 3G. Digikey still offers an evaluation board for this transformer (shown in previous picture). Datasheet may be found here: Datasheet for the ADT2-1T may be found here: While the TC1_1_13MA was setup as a current BALUN, the ADT2-1T was setup as a voltage BALUN. Attached showing the return loss of the four pairs on our 1Gb Ethernet after calibration.
