BAD CABLE, GOOD CONNECTION:

The cursor in the NEXT graph is located at the worst NEXT at 6.2 MHz, which is

outside the limit line. (For display purposes the cursor is moved to the Zero-

position.) The Link failed. Why?

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

graph.

The NEXT response from the connector located at 2 m is well within the S-

Bands and performs significantly better than the requirements. The NEXT in the

cable is the source of the failure even though the cable’s NEXT response peaks are

less than those of the connection. By knowing that the connection meets its

performance requirement, the cable is easily identified as the non-compliant

component of the link.
