Setting Up Cable IDs
The cable identification (cable ID) is the name you assign to the Autotest results
you save. You can create a cable ID each time you save an Autotest, or you can
use IDs generated as follows:
• The auto increment function generates IDs by incrementing the last
alphanumeric character in the cable ID.
• The auto sequence function generates IDs by incrementing characters through
a range of values defined by a start and end ID.
• On a DSP-4300 test tool, you can select IDs from lists downloaded to a
memory card. You can create and download the lists with CableManager
software.
Enabling the Auto Increment Function
The test tool’s auto increment function increments only the last alphanumeric
(letter or number) character of the cable identification name each time you save
Autotest results.
To enable or disable the auto increment function, proceed as follows:
1. Turn the rotary switch to SETUP.
Getting Started
Configuring the Test Tool

DSP-4000 Series
Users Manual
Determining a Range of Cable IDs for the Auto Sequence Function
Use the following guidelines when determining a range of cable IDs to use with
the auto sequence function.
• Cable IDs can contain a maximum of 18 letters, numbers, and special
characters (such as -, #, and spaces). Accented characters are not available.
• The types of characters used in each position must match between the range’s
start and end ID. For example, using the letter “O” as the third character in the
start ID and the number “0” as the third character in the end ID generates an
error message.
• The auto sequence function increments letters and numbers starting with the
farthest right character, then moving left. Special characters and matching
characters are not incremented. As an example, the following range of cable
IDs could be assigned for testing the cabling in 2 rooms where each room has
3 cable drops:
Start ID: ROOM A DROP#1
End ID: ROOM B DROP#3
The test tool would name the Autotest results in the following sequence:
ROOM A DROP#1
ROOM A DROP#2
ROOM A DROP#3
ROOM B DROP#1
ROOM B DROP#2
ROOM B DROP#3
2-38
If you try to save Autotest results after the last ID was used, the list shown after
you press S shows that all IDs are used by saved reports (used IDs are
preceded by a “$”). Use the Edit or New softkeys to create a new ID. See
Chapter 3 for more information.
Enabling and Configuring the Auto Sequence Function
1. Determine the range of cable names you want to use for your Autotests. (Refer
to the previous section.)
2. Turn the rotary switch to SETUP.
3. Use D to highlight the auto inc rem ent sett ing ; then pres s ! Choice.
4. Use DU to highlight Sequence; then press ! Edit ID Seq.
5. Use ! to select the Start ID or End ID field for editing.
6. To add characters to the ID, use the L R U D keys to highlight a character in
the list, then press E.
Use @ Â and # ³ to move the cursor through the ID.
Use $ Delete to delete characters to the left of the cursor.
7. Press S when you are finished; then press E.
When necessary, you can edit the cable ID when you save an Autotest. See

Autotest on Twisted Pair Cabling
The procedures for an Autotest on shielded and unshielded twisted pair cabling are
the same. The test tool tests shield continuity if shielded cable was selected and the
shield test enabled when the cable type was selected in SETUP.
To run the Autotest on twisted pair cabling, refer to Figures 3-1 through 3-3 and
proceed as follows:
1. Attach the appropriate link interface adapters to the main and remote units.
Refer to the table in the appendix.
2. Turn on the remote.
3. Connect the remote to the far end of the cable link. For channel testing,
connect using the network equipment patch cord.
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. Connect the main unit to the near end of the cable link. For channel testing,
connect using the network equipment patch cord.
7. Press T to start the Autotest.
Notes
Pressing T when 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 S or
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 SMART REMOTE and does not run the

Link Performance Grade Res ult (Headroom)
When an Autotest is complete, the display shows the overall result (pass or fail)
and the headroom value. Headroom is the smallest difference found between the
NEXT measurements and their limits. This number serves as a figure of merit that
reflects the overall performance of the link. Larger headroom values correspond to
better cabling performance.
To pass or fail cabling based on a minimum headroom value, enter the minimum
value as part of a custom test standard (see Chapter 6).
Worst Margin and Worst Value Results
Worst margin and worst value results are shown for frequency-dependent tests
such as NEXT, RL, ELFEXT, and ACR. Worst margin results are measurements
that came closest to the limit, or that exceeded the limit by the greatest amount.
Worst value results are the lowest measurements found, which may not necessarily
come closest to the limit.
Worst margin results for attenuation are not required by any test standard and are
not reported.

Automatic Diagnos tics
If an Autotest fails, you can press F to see more specific information on the
cause of the failure. Figure 3-4 shows examples of automatic diagnostics displays
for a NEXT failure and an open pin failure.
The arrow in the diagram at the top of the display shows the location of the failure.
The bottom half of the display describes the failure and suggests ways to fix the
fault. When appropriate, softkeys let you see the plot or plots relevant to the
failure. If more than one fault was found, you can use the $ NextFault

Resistance
The resistance test measures the dc loop resistance for each cable pair. The
resistance results screen displays the resistance, limit, and pass/fail result for each
cable pair. A PASS result means that the measured resistance is less than the
limit. A FAIL result means that the measured resistance exceeds the limit.
Length
The length test measures the length of each cable pair tested. The main Autotest
results screen shows the length of the cable pair having the shortest electrical
delay. The length results screen displays the length, limit, and pass/fail result for
each cable pair. Length is displayed in meters or feet. You can change the length
units in the SETUP mode, as described in “Selecting a Length Unit” in Chapter 2.
Notes
A 2 to 5 percent difference in measured length between twisted pairs
is typical. This difference is due to differences in the number of twists
in the cable pairs.
Differences between measured and actual values of cable length can
be caused by variations in the cable’s NVP value. NVP values can
vary among cable types, lots, and manufacturers. To ensure
maximum accuracy of length measurements, perform an NVP
calibration as described in Chapter 6.
3-10
A PASS result means that the measured length is within the specified limit for the
selected test standard. A FAIL result means that the measured length exceeds the
limit.
Propagation Delay and Delay Skew
Propagation delays are the times taken in nanoseconds for a test pulse to travel the
length of each cable pair.
Delay skews are the differences in propagation delays between the shortest delay,
which is displayed as 0 ns, and the delays of the other cable pairs.
The propagation delay and delay skew results show a limit if the test is required by
the selected test standard. If the test is not required, the results always show
PASS.
Characteristic Impedance
The characteristic impedance test determines the approximate characteristic
impedance of each cable pair.
Impedance measurements require a cable at least 5 m (16 ft) long.
Cables shorter than this length will always pass the impedance test.
A PASS result means that the measured impedance is within the specified limit
for the selected test standard. A FAIL result means that the measured impedance
exceeds the specified limit, or an impedance anomaly is detected.
Autotest Results for Twisted Pair Cabling
Note

A Warning result means that the measured impedance exceeds test limits, or an
anomaly is detected, but the characteristic impedance test is not required by the
selected test standard. The warning result causes a warning to appear as the test

NEXT@REMOTE
The NEXT@REMOTE test and its results are identical to the NEXT test described
above, except that the NEXT@REMOTE measurements are taken from the remote
end of the cabling.
ELFEXT Test
The ELFEXT (equal level far-end crosstalk) test calculates the ratio of FEXT to
attenuation for each cable pair. To determine ELFEXT, the main unit first
measures FEXT by generating a signal at the far end of the cabling and measuring
the resulting crosstalk at the near end of the cabling. ELFEXT is calculated as the
difference (in dB) between the measured FEXT and attenuation values. If the
ELFEXT test fails, you can use the F key to locate sources of crosstalk on the
cabling.
Because ELFEXT values from either end of a cable are virtually identical, a
ELFEXT@REMOTE test is not required. (See Chapter 7 for more information.)
The first ELFEXT screen displays the cable pairs tested, the worst-case ELFEXT
margin, and the test result for each set of pairs.

PSACR (Power Sum ACR) and PSACR@REMOTE
PSACR results show the ratio of each wire pair’s attenuation to the combined
crosstalk received from the other pairs. The test tool calculates PSACR values by
subtracting a pair’s attenuation from its PSNEXT value. PSACR@REMOTE
values are calculated using PSNEXT@REMOTE values.

Autotest Results for Coaxial Cabling
1. Attach a channel link interface adapter to the main unit.
2. Turn off any PC nodes connected to the cabling you are testing.
3. If you want the Autotest to report cabling length, remove the terminator from
the far end of the cabling.
4. Turn the rotary switch to AUTOTEST.
5. Verify that the test standard and cable type displayed are correct. You can
change these settings in the SETUP mode.
6. Remove the terminator from the near end of the coaxial cabling. Use the RJ45
to coaxial adapter to connect the test tool to the cabli ng .
7. Press T to start the Autotest.
Autotest Results for Coaxial Cabling
An Autotest on coaxial cabling performs the following tests:
Characteristic Impedance
Note
Impedance measurements require cabling at least 5 m (16 ft) long.
Terminated cabling shorter than this length will always pass the
impedance test. Unterminated cabling shorter than this length will
always fail the impedance test.
Autotest
3
The characteristic impedance test determines the approximate characteristic
impedance for the cable. A PASS result means that the impedance is within the
limit specified by the selected test standard. A FAIL result means that the
impedance exceeds the limit. You can use the HDTDR test to plot the locations
and sizes of all impedance anomalies on the cabling.

Resistance
The resistance test measures the loop resistance of the cabling and the terminator.
If a terminator is not connected or if the cabling is open, the resistance value is
reported as OPEN. If the cabling or the terminator is shorted, the resistance value
is reported as near 0 Ω. Resistance values over 400 Ω are reported as OPEN.
Length
The length test measures the length of the cabling when a terminator is not
connected. If a terminator is connected, the result of the length test is reported as
NOREFLECTION.
A PASS result means that the measured length is within the limit specified by the
selected test standard. A FAIL result means that the measured length exceeds the
limit.
Note
Because a cable terminator eliminates signal reflections in coaxial
cabling, the test tool cannot measure the length of terminated coaxial
cabling.
Notes
Differences between measured and actual values of cabling length
can be caused by variations in the cable’s NVP value. NVP values
can vary among cable types, lots, and manufacturers. To ensure
maximum accuracy of length measurements, perform an NVP
calibration as described in Chapter 6.
3-26
Anomaly
This result is shown at the bottom of the screen only if an impedance anomaly is
detected. The test tool reports an anomaly if 10% or more of the test signal is
reflected. The result shows the distance to the largest anomaly detected.
Saving Autotest Results
A DSP-4000 test tool can store the results of 500 or more Autotests, depending on
the test standard used. The test tool stores worst-case margins and worst-case
values for most frequency-dependant tests.
A DSP-4100 or DSP-4300 test tool with STORE PLOT DATA enabled can store
at least 250 Autotests in graphical format on a 16 MB memory card, depending on
the standard used. A DSP-4300 test tool stores results in internal memory if no
card is present. More Autotests can be saved if plot data is not included. If STORE
PLOT DATA is enabled, the saved Autotest results include plots from tests such
as the attenuation and NEXT tests. HDTDR and HDTDX plots are also saved.
Saving the plot data lets you include plots on reports uploaded to a PC and printed
with CableManager Software.
The test tool may not be able to read or store test results
on a memory card that contains other types of data (such
as music files).
If you used a permanent link test standard for the Autotest, the model number of
the personality module used on the permanent link adapter is saved with the
Autotest results and appears on printed test reports.

If Memory is Full
If the Autotest results you save fill the last available memory location, the
following message appears: WARNING! TESTRESULTMEMORYISNOWFULL. If you try to save additional test results after the memory has been
filled, the following message appears: UNABLE TOSAVE TESTRESULTS.MEMORYISFULL.
To save additional test results, you must delete one or more test reports from
memory (in SPECIAL FUNCTIONS mode) or, for a DSP-4100 or DSP-4300 test
tool, put a new memory card in the test tool. Remove the memory card from a
DSP-4300 test tool to save additional results in internal memory. (See the next
section for details.) To transfer tes t repo rt s to a PC, use the CableManag er
software included with your test tool. See “Getting Started” under Help on the
CableManager toolbar for details.
You can see how many memory spaces are available by pressing the
Memory softkey, which appears on several Autotest displays.
Saving Results to Internal Memory (DSP-4300)
If no memory card is present in a DSP-4300 test tool, test results are saved to
internal memory. Later, when you insert a memory card, the test tool lets you
choose whether or not to copy the saved results from internal memory to the
memory card. After you copy the results, the test tool lets you choose to delete or
retain the results in the internal m em o ry .
Autotest

Results are always saved on the memory card when one is present. When you view
test reports in the SPECIAL FUNCTIONS mode, reports saved on the card are
always shown when a card is present. To see the contents of the internal memory,
remove the memory card.
Notes
To avoid confusion regarding the contents of the internal memory,
save test results on a removable memory card whenever possible.
Copying results from the internal memory to a memory card can take
up to 30 minutes. Verify that the battery has at least 25 % charge
remaining or connect the ac adapter before copying the resu lt s.

The Autotest Report
With CableManager software you can upload reports to a PC for viewing and
printing. Figures 3-12 and 3-13 show examples of reports generated with
CableManager software.
You can send Autotest reports directly to a serial printer or edit the report’s
identification information in the PRINT mode. See Chapter 5, “Viewing and
Printing Saved Reports,” for complete instructions.
The overall result printed on a report can be a pass or fail, or warning. A failure of
any test required by the selected test standard produces a fail result on the report
summary. If required by the selected standard, a warning appears on reports for
twisted pair cabling if a length, impedance, propagation delay, or delay skew test
produced a warning. The warning means that the measurement exceeds its limit,
but the test standard does not fail the cabling based on that m easur em ent.

Running Individual Tests
Chapter 4 provides the following information:
• Instructions for running Single Tests on twisted pair cabling.
• Descriptions of the test results produced by the HDTDX analyzer andHDTDR test.
• Instructions for running Single Tests on coaxial cabling.
• Instructions for using the tests available in the MONITOR mode.
• Instructions for using the tone generator.
Single Tests for Twisted Pair Cabling
The SINGLE TEST mode on the rotary switch allows individual execution of
many of the tests available in the Autotest mode. SINGLE TEST mode features
two additional tests: the HDTDX (High-Definition Time Domain Crosstalk)
analyzer and the HDTDR (High-Definition Time Domain Reflectometry) test.
Chapter 4
Single tests help you isolate cable failures and quickly determine if repairs are
good. To certify a cable installation, you should run an Autotest with the
appropriate test standard.

Scanning Function
The Single Test versions of the wire map, resistance, HDTDR, and HDTDX
analyzer tests include a scanning function, which you can activate by pressing the
#ScanningON softkey. The scanning function runs the test repeatedly and
updates the display each time a test is complete. This function is useful for finding
intermittent problems on a cable.
To extend battery life, connect the ac adapter/charger when using
the scanning function for more than 1 minute.
When to Use a Remote Unit
A remote unit is required only when testing twisted pair cabling. Table 4-1 shows
which cable tests require a remote and which remotes support each test.
If a remote unit is detected at the start of a Single Test, the test tool runs a wire
map test before running the selected test. If the wire map test fails, the test tool
stops the test and displays the wire map. Press $ ContinueTest to run
the selected test.
Note
Note
The DSP-4100 and DSP-4300 test tools are compatible only with
DSP-4100SR and DSP-4300SR remote units, respectively. The DSP4100 and DSP-4300 remotes are not compatible with DSP-100,
DSP-2000, or DSP-4000 test tools.
