6.3.2TDNXT EXAMPLES

The following examples show the diagnostics process that is performed to identify failures on typical links with 2 meter test cables.

GOOD CABLE, BAD CONNECTION:

The cursor in the NEXT graph is located at the worst NEXT at 144.0 MHz, which is outside the limit line. (For an easier interpretation the cursor was moved.) The Link failed. Why?

Press to open the TDNXT screen to further review and diagnose the graph.

The cursor is positioned at the worst peak, which is outside the S-Bands.

Looking at the TDNXT graph we can reach the conclusion that the connection located at 2 meters did not meet the required performance and is the cause of failure.
