3. INTRODUCTION
The NETPROBE 2000 is a lightweight, battery-operated test set optimized for monitoring,
testing and troubleshooting Gigabit Ethernet, PDH(E1, E3) , DS1(T1), DS3(T3), Datacom,
CO-DIR, Wi-Fi, VoIP, IPTV, and IEEE C37.94 telecom services. Depending on the actual
configuration ordered, some of these interfaces will not be available in the tester.
This user manual describes the NETPROBE 2000 and provides instruction on how to set it
up and perform tests.
The NETPROBE 2000 test set is menu driven and operated from a touch panel Graphical
User Interface.
Test results are safely accumulated and stored in the nonvolatile memory.
The NETPROBE 2000 is powered by either an external 12VDC adapter or from the
rechargeable long life Lithium Ion Polymer battery. Depending on the number of applied
recharge cycles the battery does not need replacement for several years. Net Research
factory provides instructions how to reinstall the new battery as self service.

4. DESCRIPTION
4.1 External Interfaces
4.1.1 Top Control Panel
The diagram to the right shows a fully equipped
NetProbe 2000 with optional Gigabit and IEEE
C37.94 ports.
The standard features include the USB port and
Audio micro connector.
The optional datacom connector supports RS-232,
RS-530, RS-449, V-35 and X.21 interfaces with an
adaptor cable. It can also support the optional G.703
Co-dir interface with an adaptor cable.
Both the Datacom (NP2000-DCOM) and G.703 Co-Dir (NP2000-CODIR) options perform Bit Error Test via the DATACOM
connector. This connector acts also as a printer port to a RS-232 thermal printer, model DPU-40.

4.1.2 Test Interface Signal Panel
The Signal Panel is used for the PDH (T1, E1, T3, and E3) interface connectors. There are many possible configurations
available to accommodate these interfaces.
The NetProbe image below is configured with a RJ-45
connector for T1/E1 and COAX connectors for T3/E3.
Both RJ-45 (balanced 100/120 Ohm) and BNC (75 Ohm) or
Bantam ( unbalanced 100/120 Ohm) connectors carry
E1/T1 signal or when equipped, the G.703 64kbps Co-Dir.
Also, the E3 and T3 signals are available via the BNC
connectors.
The PDH interfaces along with their line impedance (75 Ohm, 100 Ohm, 120 Ohm) are all user-selectable.
Page 19

4.1.3 Front Control Panel
The front Control Panel accommodates a 3.5” LCD touchscreen and
the 5- way navigation switch assembly.
The 4 arrows of navigation switch allow an alternate way to control
the cursor position and the OK button selects the item pointed by
the cursor on the LCD display.
Additionally, the OK button serves as a power ON/OFF button.
Pressing the OK button for at least 2 seconds turns power ON;
pressing it again for 3 seconds opens a menu that allows the user to
turn power OFF. Optional Power OFF is accomplished via the
Toolbar Soft Power button, which shuts down all processes and
powers down the tester.
Alternatively, hardware Power OFF can also be accomplished by
holding down the OK button for 60 seconds.

6.6 Pulse Shape Analysis (PSA)
Run the Pulse Shape Analysis (PSA) application to check if the T1 pulse shape complies with ITU-T G.703 specifications.
To plot and analyze the T1 pulse shape, first connect the T1 signal to be tested and select the appropriate Termination
from the T1 Setup menu. Press to start the PSA test.
If the pulse can be normalized it will plot inside the G.703 template. If
the pulse fits 100% inside the template, the test PASSED ( ). If any
part of the plot of the plot falls outside of the template, the test
FAILED ( ).

6.7 DS0 Testing
Run the DSO Testing application to measure the frequency and power of any received tones and monitor the ABCD bits
of a DSO sub channel. The application also allows you to listen to the audio in a timeslot using the supplied headset.
To run a DSO test, connect the T1 signal to be tested, select a timeslot number, select PCM Companding (u-Law/A-Law)
and press to start a DSO test.
DS0 testing includes:
• Listening to any of the 24 DS0 Voice Channels using
the supplied headset.
• Measuring the frequency of the received signal. Test
tones are typically 404Hz, 1004Hz, and 1804Hz.
• Measuring the power (dBm) of the received test
tones. If the reading is not available, N/A will display.
• Reading the ABCD bits for the selected timeslot.
• Transmitting signal 300-3404Hz, -40.0-3.0dBm.
• Configuring ABCD bits for the selected timeslot.

7.3 Bit Error Testing (BERT)
Run the BERT application to check the integrity of a T3 (DS3) circuit. It can be run with a loopback or end to end with
another test set. The indicators at the top display the current and historical state of
SIGNAL/FRAME/ALARM/ERROR/PSYNC events. The test results are reported as errors or error rates. Any events,
including Alarms and G.821 metrics, are also reported.
Before you start transmitting with the button, you can easily select a test pattern. In the example below, a test
pattern of 2e15-1 is selected with no inversion.
A default BERT test pattern is 2
-15-
1. Other patterns can
be selected from the list by scrolling left or right. Choices
include OFF, 63, 511, 2047, 2-15-1, 2-21-1, 2-23-1, QRSS,
All 0’s, All 1’s, 1:3, 1:7, 1:15, 1:31. The pattern can also be
configured in Setup.

Check the BERT main screen and observe the following:
Tip:
Click on any history indicator box
to reset all history indicators.
• The real-time SIGNAL, PSYNC and FRAME
(with Framed data) indicators at the top of
the screen are Green. Red indicates a
problem. If these indicators are red, should
check all circuit connections and T3 setup.
• The history indicators below are gray. Red
indicates a problem. If an event
(SIGNAL/FRAME/ALARM/ERRROR/PSYNC)
occurs, the corresponding gray history area
will remain red until it is reset.
• Error counters report 0 or at least are not
quickly incrementing. If these are quickly
incrementing, check all circuit connections
and T3 setup.
