4.
Attach the BNC connector of the cable to be tested to the female
BNC connector on the Ranger™ TDR.
OBTAINING NVP VALUES
There are three ways to obtain NVP values for a cable.
1.
The NVP can usually be obtained by checking the cable specifications
or contacting the manufacturer.
2.
The NVP can be estimated based on the type of cable (RG6, Cat5e,
etc.) using the chart on page 13.
3.
The NVP can be calculated using a known length of the cable that
will be used during testing.
•
Calculating an NVP:
1.
Prepare a length of the same type of cable for which you need to
determine the NVP.
2.
The Ranger™ TDR can calculate an NVP from a test cable length
of 25~1000ft (10~300m). Longer test lengths will give more
accurate results. It is recommended to use at least 50ft (20m).
50ft (20m) is the default setting in Calibration Mode.
3.
Determine the physical length of the test cable length. Use the
markings on the cable, a tape measure, laser distance meter, etc.
4.
Connect the test cable length to the Ranger™ TDR as described in
"Preparing to Test Cables" section.
5.
Press the Power button on the Ranger™ TDR.
6.
Press the Calibration button.
7.
Select the unit of measurement (feet or meters) by pressing and
holding the Memory and Calibration buttons at the same time.
8.
Enter the known cable length using the Calibration button and Up
and Down buttons. The Calibration button adds 50ft (20m) with
each press. The Up and Down buttons increase or decrease the
distance by 1ft or 1m per press.
9.
Press the Test button. After a few seconds, the calculated NVP
will appear in the bottom left corner of the LCD.
10.
Press and hold the Memory button to save the new NVP in the
current storage location (M1 or M2).
11.
If the calculated NVP is outside of the range 20.0 to 99.9, the LCD
will display "Error".

Step 9
Step 11
SETTING NVP VALUES
The NVP value must be set correctly in order to obtain an accurate length
measurement from the device.
•
Manually Setting NVP:
1.
Press the Power button. The unit will start up in Test Mode.
2.
Use the Up and Down buttons to set the NVP value shown in the
lower left hand corner of the LCD screen.
3.
Pressing and holding a button will change the value more quickly.
•
Saving NVP:
1.
The Ranger™ TDR has two storage locations for NVP values.
2.
Press the Memory button repeatedly to toggle between memory
locations.
3.
Set the memory location using the procedure noted above.
4.
Press and hold the Memory button. The up and down arrows
shown on the LCD screen will disappear when the new value has
been stored.
5.
Recall a stored value by pressing the Memory button until the
desired memory location is shown.
TESTING CABLE & DETERMINING LENGTH
Once a cable's NVP value has been set, the cable length can be determined
using Test Mode. As stated in
Preparing to Test Cables,
the cable to be
tested should be left open on the opposite end from the tester.
A cable
terminated with an impedance closely matching the characteristic
impedance of the cable can produce inaccurate test results.
•
Testing Cable:
1.
Attach the cable to be tested as instructed in
Preparing to Test
Cables
section.
Cables section.Cables

11
2.
Note that the connection to the cable to be tested should be as
short as possible to ensure the Ranger™ TDR does not see the
impedance continuity at the attachment point as a fault.
3.
Determine the correct NVP value for the cable to be tested as
instructed in
Obtaining NVP Values
section.
Obtaining NVP Values section.Obtaining NVP Values
4.
Set the NVP value as instructed in
Setting NVP Values
section.
Setting NVP Values section.Setting NVP Values
5.
Turn the unit on by pressing the Power button.
6.
Change the unit of measurement if necessary by pressing and
holding the Memory and Calibration buttons at the same time.
7.
Press the Test button once. After a moment, the calculated length of
the cable will appear in the upper right hand corner of the screen.
8.
The screen will display "Short" if the two conductors are directly
connected or have a low resistance connection between them.
The length will be shown up to the shorted point.
9.
The screen will display "Open" if the two conductors are not
directly connected or have a high resistance connection between
them. This is the normal condition for performing length testing.
If there is an unexpected open condition along the length of the
cable, only the length up to that point will be displayed.
10.
The screen will display "Error" and show dashes instead of the
length if an error condition has occurred. This could be because
the cable is improperly terminated or there has been excessive
signal loss.
Step 7
Step 10
•
Using Loop Testing Mode:
The Ranger™ TDR can run continuous tests when set to Loop Mode.
Loop Mode can help when testing long cable runs susceptible to
signal loss, and enabling you to test multiple cables without having to
press the Test button each time.
1.
While in Test Mode, press and hold the Test button.
2.
The screen will momentarily flash "LOOP", then run a test every
two seconds and display the results.
3.
Pressing any other button except the Power button exits
Loop Mode.

Velocidad de
propagación
nominal (VPN)
Conocida también como velocidad de
propagación (VDP), factor de velocidad (FV) y
velocidad de propagación de las ondas, la VPN
es la velocidad de una señal eléctrica que viaja
por un cable, medida como porcentaje de la
velocidad de la luz.
Tensión extrabaja
de seguridad
(TEBS)
La TEBS es una calificación determinada por
la Comisión Electrotécnica Internacional, que
define los estándares de tensión segura cuando
se utilizan dispositivos electrónicos. La TEBS
es 60 V para sistemas de CC y 42,5 V de valor
eficaz (RMS) para sistemas de CA.
Conector F
Un conector F es un conector común para
un cable coaxial, asociado a menudo con
televisores.
Reflectometría
en dominio
de tiempo
de espectro
ensanchado
(TDR-SS)
El espectro ensanchado es la base tecnológica
de las comunicaciones de los teléfonos celulares
y se utiliza para transmitir señales pequeñas en
entornos con niveles elevados de ruido. Al
combinar el espectro ensanchado con la
tecnología TDR, la TDR-SS permite realizar una
prueba de longitud en cables sin interferencia de
la tensión.
