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 run an Autotest on coaxial cable, refer to Figure 2-3 and proceed as follows:

1.Turn off any PC nodes connected to the cable you are testing.

2.If you want the Autotest to report cable length, remove the terminator from the far end of the cable.

3.Turn the rotary switch to AUTOTEST.

4.Verify that the test standard and cable type displayed are correct. You can change these settings in the SETUP mode.

5.Remove any cable connected to the test tool’s unused RJ45 connector.

6.Remove the terminator from the near end of the coaxial cable and connect the cable to the BNC connector on the test tool. On Model DSP-2000, use the RJ45 to BNC adapter to connect the cable to the CABLE TEST jack.

7.Press T to start the Autotest.
