100Base-TX Tests

The 100Base-TX signal is an MLT-3 signal, that is, symbols are encoded into one of three voltage levels on the

twisted pair (+1, 0, and -1 V). The electrical requirements for this signal are defined in the ANSI X3.263-1995

standard for FDDI interfaces. The tests required by the standard are listed in the

100Base-TX [ANSI X3.263-

1995]

section (previous).

To run the full set of 100Base-TX tests, choose the 100BASE-TX All tests configuration in QualiPHY.

If the test needs to be run manually, use the following procedure:

1. From the menu bar, select Analysis  Ethernet Tests

2. Touch the 100Base-TX button on the left side of the menu to select the 100Base-TX test mode.

The 10Base-T test area of the TF-ENET-B also allows for devices to be tested using a link partner. See the Link

Partner Testing for 10Base-T & 100Base-TX topic of this manual.
