Key Features
The NetTek YBT100 and NetTek YBT100DS3 Backhaul Testers are
state-of-the-art, comprehensive, test modules for testing DS1 and DS3
services. The functionality and user-friendly design allows you to
easily analyze and resolve problems that arise in a n etwork. These
lightweight, battery powered instruments combine all the test interfaces
needed to test and troubleshoot copper services without the need for
plug-in modules. The YBT100 or Y B T100DS3 can operate either
independently (to log measurements/events) or from a PC or NetTek
Y400 Analyzer Platform. Features include:
Part of the NetTek Toolbox, which provides a portable and
full-featured transmitter, antenna, and backhaul testing solution
Controlled using the NetTek Y400 Analyzer platform, a PC, or a
laptop, or can be left on-site to monitor signal events
Wireless 802.11 b/g connection lets you operate the YBT100 or
YBT100DS3 from a laptop without a direct connection, such as
from a vehicle in bad weather
Display elements show all test results on the main screen, with
color coding to make pass/fail testing viewable fro m across a room
Easy-to-use interface with key settings accessible from the main
application screen, or within one or two clicks
Two fully independent DS1 test interfaces (YBT100 and
YBT100DS3), and an optional DS3 test interface (YBT100DS3),
with monitoring, error insertion, and loop test capabilities

Configuration
NOTE. Throughout the rest of the manual, the term YBT100 refers to both
the NetTek YBT100 and the NetTek YBT100DS3 modules. When instructions
or information is specific to a particular model, the specific model is called
out in the text.
Power
Connecting the AC Adapter. Do the following to install the AC power
adapter and charge the batteries:
1. Insert the AC power adapter mini-jack into the instrument. See 1
in the next figure.
2. Connect the AC adapter m odule to an AC pow er source. The
yellow Charge LED on the instrument lights to indicate that the
instrument battery is charging. The LED turns off when the battery
is charged. See 2 and 3 in the next figure.
3. Charge the Lithium-Ion battery for eight hours before using t he
instrument on battery power for the first time. A full charge from a
discharged battery requires approximately six to eight hours.
Powering On and Off the Instrument .
1. Move the Power On switch in the up direction to power on
the YBT100. The green power LED lights to indicate that the
instrument is powered on.
2. To power off the instrument, move the switch in the do wn direction.

Getting Started
Running on Battery Power. The following are guidelines for operating
the YBT100 from battery power:
The AC adapter charges the battery pack and supplies power to
the module.
The battery charge circuit is independent of the power state
(On/Off) of the instrument.
A full charge from a discharged battery requires approximately
sixtoeighthours.
How long the instrument can run on battery power depends on
the num ber of active test interfaces (DS1-A, DS1-B, and DS3)
that are running. The battery supports a single test interface for
approximately 8 hours of continuous operation. Multip le test
interface selections decreases the battery life by about 30% for
each active interface.
Setting Up Communications to a PC or NetTek Y400
You must connect the YBT100 module to a PC or NetTek Y400 to
configure the YBT100 to monitor or insert signals. You can connect the
YBT100 module to a PC using a wireless 802.11 b/g connection, or to a
PC or NetTek Y400 Analyzer Platform by using the supplied YBT100
to PC RS-232 adapter cable (Tektronix part number 012-1706-XX).
Setting Up the Wireless 802.11 b/g Connection.
NOTE. Each PC 802.11 b/g implementation is different (built-in, PCMCIA
card wireless adapter, USB-port wireless adapter, PCI card). Use the
instructions that come with your PC or WiFi adapter to set up and enable
your 802.11 unit. The following instructions use the Microsoft Windows XP
Wireless Network Connection utility to configure your PC to use 802.11 b/g
to communicate with the YBT100.
1. Enable the 802 .11 communications device on your PC. Consult
your PC manual or WiFi adapter manual for instructions.
2. Connect the 802.11 antenna to the YBT100 module antenna
connector.
3. Power on the YBT100 module.
