Autotest on Twisted Pair Cable

Autotest on Twisted Pair Cable

Autotest performs all of the tests necessary to determine if the cable you are testing meets the test standards specified for your LAN installation.

The following tests apply to twisted pair cable:

∙Wire Map

∙Resistance

∙Length

∙Propagation Delay

∙Delay Skew

∙Impedance

∙NEXT (Near-end Crosstalk)

∙Attenuation

∙ACR (Attenuation to Crosstalk Ratio)

∙RL (Return Loss)

∙PSNEXT (Power Sum NEXT; Model DSP-2000 only)

Some test standards require a NEXT measurement from both ends of the cable. If you are using another main unit (Model DSP-100 only) or a smart remote as the remote unit, and you enable remote end testing on the main unit, the Autotest runs the REMOTE tests supported by the test tool if those tests apply to the selected test standard.

To Autotest twisted pair cable, refer to Figure 2-2 on the next page and proceed as follows:

Note

Standard remote units do not support remote end testing.

Note

If the calibration message appears after you start the Autotest, refer to “Calibrating the Test Tool” in Chapter 6 for complete calibration instructions.
