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 from 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),

Getting Started
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 module to an AC power 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 the
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 down 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 number 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. Multiple 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.

Getting Started
Disabling the YBT100 Wireless Connection. UseyourlaptoporPC
wireless connectivity tools to disconnect or close the 802.11 b/g wireless
connection.
Setting Up the Serial Cable Connection.
CAUTION. Use only the supplied YBT100-to-RS-232 cable. Do not use a
standard USB cable to connect from the YBT100 RS-232 port to a USB port
on a PC or other device. The signal on the RS-232 port of the YBT100 is
not a USB signal. The YBT100 RS-232 connector pinouts, signal types, and
voltage types are not compatible with standard USB connectors and could
damage one or both pieces of equipment. If your PC does not have an
RS-232 connector, obtain an RS-232 to USB adapter to connect the RS-232
end of the cable to the PC USB port.
1. Connect the USB-style connector of the supplied YBT100
USB-connector-to-RS-232 cable into the YBT100 RS232 port on
the module rear panel.
2. Connect the DB9 RS-232 connector to the PC or Y400 COM1
RS-232 port.
3. Start the YBT100 application on the PC. The YBT100 application
displays No Comm Link to the right of the speaker on/off button.
4. Power on the YBT100 module. The YBT100 application
automatically recognizes and establishes communications with the
YBT100 instrument over the RS-232 cable, and replaces the No
Comm Link message (adjacent to the Spkr on/off button) with
ET: n:n:n, indicating the time period of the current test run.
You can also verify that the YBT100 application is communicating
with the YBT100 module by looking at the instrument rear panel
status LEDs. The Link Fault LED will be off, and the Rx and Tx
LEDs will be blinking.
