The Return Loss response from the connector located at 2 m is well within the

connection meets its performance requirement, the cable is easily identified as the
non-compliant component of the link.
The following table summarizes the typical diagnosis process.

S-Band limits
PASS N/A Return Loss of link is good

reterminate. Plug and/or jack can be at
