Test
HDTDX analyzer
Recommended. Without a smart remote, results for short cables may be unreliable.
HDTDR analyzer
Optional. Without a smart remote, the plot shows large reflections at the end of the cabling.
Recommended. Without a remote some faults, such as split pairs and opens at the far-end connector,
Wire Map
cannot be detected.
AC Wire Map
Required. See Chapter 4.
Resistance
Optional.
Impedance
Optional. Test is available only for limits that require the impedance measurement.
Length
Optional.
Propagation Delay
Optional.
Delay Skew
Optional.
Insertion Loss
Required.
Recommended. The NEXT test may fail if the end of the cabling is not properly terminated with a
NEXT/PS NEXT
remote or resistors.
ACR-F/PS ACR-F
Required.
ACR-N/PS ACR-N
Required.
Recommended. The return loss test may fail if the end of the cabling is not properly terminated with a
Return Loss
remote or resistors.
* Note: If a remote is not required for a test, the test runs without activating the toner when no remote is detected.
