Causes of Coaxial Test Failures

Table 8. Causes of Coaxial Test Failures
Resistance test gives a FAIL, FAIL*, or PASS* result
 Link is too long (may need to remove coiled service loops)
 Bad connection due to oxidized or loose contacts
 Wrong type of patch cord used
 For tests on terminated cable, the terminator's resistance is incorrect
The HDTDR analyzer can help you locate the cause of
a resistance failure. See "The HDTDR Analyzer" on
page 127.
To do the resistance test continuously while you look
for a fault, tap TOOLS > Single Tests > Resistance.
Length gives a FAIL result
 Link is too long (may need to remove coiled service loops)
 NVP is set incorrectly
To do the length test continuously while you look for
a fault, tap TOOLS > Single Tests > Length.
Length gives an End Not Found result
 A terminator is connected to the far end of the cable
 The cable is connected to a splitter
Propagation delay gives a FAIL result
Link is too long (may need to remove coiled service loops)
Insertion loss gives a FAIL, FAIL*, or PASS* result
 Link is too long (may need to remove coiled service loops)
 Poor quality patch cord
 Bad connection
 Wrong cable type in the installation
 Wrong test standard selected
