OMNISCANNER

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

The Return Loss response from the connector located at 2 m is well within the S-Bands and performs significantly better than the requirements. The Return Loss in the cable is the source of the failure even though the cable’s Return Loss 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.

The following table summarizes the typical diagnosis process.

Return Loss	TDRL exceeds	Conclusion
	S-Band limits
PASS	N/A	Return Loss of link is good
FAIL	YES	Connection fails. Replace or
		reterminate. Plug and/or jack can be at
		fault.
FAIL	NO	Cable is not within specifications
