Autotest on Twisted Pair Cable

Note

The REMOTE tests will run only if the remote is a smart remote or a DSP-100 with the SMART REMOTE mode selected.

1.If you are using a DSP-100 main unit as the remote, turn the remote unit’s rotary switch to SMART REMOTE. If you are using a smart remote unit, turn its rotary switch to ON.

2.Use a 2m patch cable of the correct impedance to connect the remote to the far end of the cable link.

3.On Model DSP-100, remove any cable connected to the test tool’s BNC connector.

4.Turn the rotary switch on the main unit to AUTOTEST.

5.Verify that the settings displayed are correct. You can change these settings in the SETUP mode.

6.Use a 2m patch cable of the correct impedance to connect the test tool to the near end of the cable link. On Model DSP-2000, connect to the CABLE TEST jack.

7.Press Tto start the Autotest.

Notes

Pressing Twhen the previous Autotest was not saved causes the test tool to display a warning message. In this case, you can either save the results of the previous test by pressing Sor delete the results and start a new Autotest by pressing T.

If a remote is not connected, the test tool displays the message SCANNING FOR REMOTE and does not run the Autotest until a remote is connected.

If the calibration message appears, refer to “Calibrating the Test

Tool” in Chapter 6 for complete calibration instructions.
