Preface
The NetTekRYBT250 Field Transmitter & Interference Tester is
part of the NetTek Base Transceiver Station (BTS) Field Tool family:
a high performance, portable, field-ready tester optimized for fast
trouble resolution and easy BTS performance verification. It is based
on the familiar and easy-to-use Windows CE operating system, so
you will spend less time learning the instrument and more time
troubleshooting the network.
The YBT250 verifies the most important RF transmit functions of
cdmaOne/cdma2000/1xEV-DO, TDMA IS-136, GSM/EDGE,
W-CDMA (UMTS), and Analog base stations. The YBT250 Field
Transmitter & Interference Tester has powerful analysis tools to
enable you to locate and identify interfering signals quickly. With its
built-in spectrum analysis display, the YBT250 enables you to easily
see signal problems. The spectrogram display makes it easier than
ever to spot intermittent signal problems.
About this Manual
This manual is divided into four sections: Getting Started, Operating
Basics, Reference, and Appendices.
The Getting Started section describes how to start using your
YBT250 Field Transmitter & Interference Tester.
The Operating Basics section shows you how to operate the
YBT250.
The Reference section explains how to perform specific tests with the
YBT250.
The Appendices contain reference information such as specifications,
a functional verification procedure, and other information that you
might need occasionally.

Installing and Removing a Module
If you purchased the YBT250 Application Module as a separate
item, you must install the module on a NetTek Analyzer platform
before you can take measurements. Refer to Figures 1--4 and 1--5 to
install or remove an application module.
CAUTION. To prevent damage to the NetTek Analyzer Platform or an
application module, you must power down the NetTek Analyzer
Platform and remove all cables or connectors before installing any
application module.

Batteries
Installing or Removing a Battery
The NetTek Analyzer Platform comes standard with a single battery,
which is not installed when the instrument is shipped. Refer to
Figures 1--7 through 1--9 for battery installati o n or removal steps.
NOTE. Disconnect power supply cables from the NetTek Analyzer
Platform before installing or removing batteries.
New batteries, or batteries that have not been used for an extended
period, must be charged before using them to power the instrument.

Install the battery in either slot. You can add a second battery to
increase the operating time. Replace a battery with the specified type
only. To purchase a battery from Tektronix, please contact your
Tektronix Service Center for the correct part number.
Charging a Battery
To charge batteries, connect the instrument to an external power
supply (see Figure 1--6 on page 1--6) and let the battery or batteries
recharge in the instrument. Table 1 --1 lists the approximate charge
times for fully--discharged batteries. You can also charge batteries in
the optional external battery charger.

NOTE. To achieve optimum performance from a new battery, fully
charge the battery. Then fully discharge the battery by leaving the
NetTek Analyzer Platform and application modules running (see

Getting Started
Batteries are partially charged and calibrated at the factory. A
calibrated battery allows the NetTek Analyzer Platform to more
accurately estimate how much longer application modules can
operate before the instrument automatically powers off. The NetTek
Analyzer Platform always warns you before it powers off, so that
you can save important test results or settings.
To verify the status of your batteries at any time:
1. Select Start > Settings > Control Panel.
2. Double-tap the Power Management icon. The Batteries tab lists
If the battery charge is low, connect the NetTek Analyzer Platform to
an external power source and let the battery or batteries recharge in
the instrument for eight hours. For more information, select Start >

Transporting Lithium-Ion Batteries
Regulations regarding transportation of lithium-ion batteries on
passenger aircraft may subject this product to special handling
restrictions. Consult your air carrier for applicability and determination of any special lithium-ion battery transportation requirements.
Each NetTek Analyzer Platform lithium-ion battery pack contains
less than 8 grams of lithium, with individual cells each containing
less than 1.5 grams of lithium, as measured by International Civil
Aviation Organization (ICAO) standards.
Battery Recycling
The NetTek Analyzer Platform uses replaceable Lithium Ion
batteries, which must be recycled or disposed of properly at the end
of product life. There may be specific legal requirements in your
community for battery collection and disposal. Contact your local
electronics recycler, relevant legal authority, or your Tektronix
representative for assistance in recycling batteries.
