Users Manual

Return Loss (RL) and RL@REMOTE

The RL test is identical to the Autotest version. See “Return Loss” in Chapter 3 for details.

The RL@REMOTE test is available only when using a DSP-2000 with a DSP- 2000 smart remote. Remote end testing must be enabled on the main unit. See "RL@REMOTE" in Chapter 3 for details.

Single Tests for Coaxial Cable

The Single Test mode on the rotary switch allows individual execution of the coaxial cable tests available in the Autotest mode. The TDR test is also available as a Single Test for coaxial cable.

The coaxial cable tests available as Single Tests produce results displayed in the same format as displayed in the Autotest mode.

Running a Single Test on Coaxial Cable

Note

For instructions on running the TDR test, see the earlier section “The TDR Test.” For instructions on running tests in the MONITOR mode, see the later section “Monitoring Network Activity.”

To run a Single Test on coaxial cable, refer to Figure 4-4 and proceed as follows:

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

2.If you want to measure cable length, remove the terminator from the far end of the cable you are testing.

3.Turn the rotary switch to SINGLE TEST.

4.Verify that the test standard and cable type 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 this end of 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.Use UDto highlight the test you want to run.

8.Press Eto start the highlighted test.
