YBA250 Antenna and Transmission Line Analyzer User Manual
Preface
The YBA250 Antenna and Transmission Line Analyzer is part of the
NetTek Analyzer Platform BTS Field Tool family. This high
performance, portable, field-ready tester is optimized for fast trouble
resolution and easy BTS antenna and tower mounted amplifier
(TMA) performance verification.
Product Overview
The standard YBA250 configuration consists of two components; the
YBA250 application module and the NetTek Analyzer Platform. The
application module contains the hardware and software needed to
analyze antenna characteristics and performance. The NetTek
Analyzer Platform provides the power and user interface to run the
YBA250 application module software and hardware. The YBA250
can be purchased separately to install on a NetTek Analyzer Platform
that you already have.
The YBA250 Antenna and Transmission Line Analyzer application
features include:
H One-port Return Loss and VSWR measurements to quickly
analyze a system
H One-port Cable Loss measurement to analyze system cable
characteristics
H One-port distance-to-fault (DTF) measurement to identify t he
location
H Two-port Insertion Gain and Loss measurements to an alyze the
characteristics of active components (such as TMAs and
directional couplers) and passive devices (such as bandwidth
filters and cables)
H Advanced calibration and normalization techniques to eliminate
the need to perform a calibration each time the frequency or
display range is changed
YBA250 Antenna and Transmission Line Analyzer User Manual
xi
Preface
H User-defined calibration and normalization data sets for testing
and measuring specific frequencies and power levels
H User-defined test masks to provide fast pass/fail testing of
antenna, device, or system performance
The NetTek Analyzer Platform user interface uses the Microsoft
Windows CE operating system, so you spend less time learning the
instrument and more time troubleshooting the network. Key NetTek
Analyzer Platform features include:
H High-visibility color display with a touch-screen interface
H Extendible instrument architecture lets you add other NetTek-
compatible measurement modules (up to three) as your testing
and troubleshooting needs change
H Ruggedized package for real-world testing conditions
H Removable battery packs to extend in-field testing time
H I/O ports connect the instrument to a printer, an external
keyboard, and the Internet
H Two PCMCIA card slots for adding storage memory, additional
measurement capabilities, and using PCMCIA Ethernet and
modem cards to connect to a network or the internet
H Software applications and utilities that support communications,
power management, instrument configuration, text editing, Web
browsing and more
