Chapter 1 provides the following information:
• Features of the DSP-100 and DSP-2000 test tools.
• A list of equipment included with the test tools.
• A guide to using this manual.
Overview of Features
The Fluke DSP-100 LAN CableMeter® and DSP-2000 LAN Cable Analyzer test
tools (hereafter referred to collectively as “the test tool”) are hand-held
instruments used to certify cable and to test and troubleshoot coaxial and twisted
pair cable in local area network (LAN) installations. The test tool features new
measurement technology that combines test pulses with digital signal processing
to provide fast, accurate results and advanced testing capabilities.
Chapter 1
Introduction
The test tool includes the following features:
• Checks LAN cable performance against IEEE, ANSI, TIA, and ISO/IEC
standards.
• Presents test options and results in a simple menu system.
• Presents displays and printed reports in English, German, French, Spanish, or
Italian.
• Runs all critical tests automatically.

Chapter 2 provides the following information:
• Safety and cautions to observe when using the test tool.
• Instructions for getting started quickly with the test tool.
• Detailed information on the test tool’s features.
• Detailed instructions on configuring the test tool.
Safety and Operational Information
The international electrical symbols used on the instrument or in this manual are
described in Table 2-1.
Table 2-1. International Electrical Symbols
Warning: Risk of electric shock.
Warning or Caution: Risk of damage or destruction to equipment or software. See
explanations in the manual.
Equipment is protected by double insulation or reinforced insulation to protect the user
against electric shock.
Do not connect this terminal to public communications networks, such as telephone
systems.
Battery should be recycled. Refer to "R eplacing the NiCad Battery Pack" in Chapter 8.

Users Manual
XWarning
To avoid possible fire or electric shock w hen chargi ng t he
battery or powering the test tool w ith ac power, use only
the ac adapter/charger provided with the test t ool.
WCaution
Never connect the test tool to telephone l ines of any type,
including ISDN lines. Doing so can damage the test tool.
• Always turn on the test tool before connecting it to a cable. Turning the test
tool on activates the tool’s input protection circuitry.
• Except when monitoring network activity, never connect the test tool to an
active network. Doing so may disrupt network operation.
• When using a coaxial T-connector to connect the test tool to a network, never
allow the T-connector to touch a conductive surface. Such contact may disrupt
network operation.
• Never attempt to insert any connector other than an RJ45 connector into the
RJ45 jack. Inserting other connectors, such as RJ11 (telephone) connectors,
can permanently damage the jack.
• Never attempt to send data from a PC to the test tool while running a cable
test. Doing so may cause erroneous test results.
• Never operate portable transmitting devices during a cable test. Doing so may
cause erroneous test results.
• Never run tests with cables connected to both test connectors. Doing so may
cause erroneous test results.
• To ensure maximum accuracy of test results, perform the self-calibration
procedure as described in “Calibrating the Test Tool” in Chapter 6.

Quick Start
This section is for users who want to start using the test tool immediately with
minimal instruction. For suggestions on additional reading that may be helpful to
you, see “Using this Manual” in Chapter 1.
Powering the Test Tool
Before powering the test tool or smart remote with the NiCad battery pack, charge
the battery for about 3 hours. To charge the battery, connect the ac adapter/charger
to the test tool or smart remote and to ac line power. You can operate the unit on
ac power while the battery charges. A fully-charged battery typically lasts 10-12
hours. See “Battery Status” on page 2-31 for information on battery status
messages.
The ac adapter/charger will not power the test tool when the battery
pack is removed.
The standard remote unit is powered by a 9V alkaline battery. The test tool
monitors the remote unit and alerts you when the battery voltage is low.

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.
Getting Started

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 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.
