Y400 NetTek Analyzer

Handheld Platform
The Tektronix NetTek® analyzer is a revolutionary portable field tool. When combined with various test modules, the NetTek offers proven measurement capability at a surprisingly low price, in a rugged, easy-to-use package, suitable for all field environments.

Easy To Use
The NetTek analyzer is based around the familiar Windows CE operating system. As a result, users will spend less time learning the instrument and more time troubleshooting the network. Furthermore, built-in help guides speed the measurement process. Common measurements have been optimized for quick, repeatable results. For example, novice users can display results with straightforward Windows-like zoom and resize controls.

Enhanced Productivity
Used in conjunction with the NetTek® Analyzer, the NetGuide software solution enables creation of customized procedures that allow for consistent testing among technicians. Be assured of proper measurement configuration by defining step-bystep instructions for the user. Guarantee that all tests are executed to company standards. Share expert knowledge among your technicians to minimize network down time.

Touch Screen
The Windows CE interface is combined with a rugged touch screen. User controls and buttons only appear on the screen when they are needed, making measurements simpler to perform. The screen is operated by pressure, meaning that even a gloved finger can reliably operate the instrument in cold weather.

Field Rugged
The NetTek analyzer is designed to withstand day to day abuse wherever testing is required. The NetTek analyzer and each module feature a magnesium alloy shell, bonded with a rubber skin for maximum impact resistance and rigidity. All ports feature a sealed rubber cover. The unit may be operated and stored over a wide temperature range.

The NetTek analyzer design needs no fan or ventilation ports, maximizing resistance to dirt and dust.

PC Connectivity
The NetTek analyzer is designed to easily work with the PCs required for maintaining today’s networks. The instrument includes as standard two PC card slots, Ethernet port, RS-232 port and USB slots. A USB floppy disk drive or PCMCIA memory card can be added as an option. The NetTek can also be controlled remotely using the optional Virtual CE interface. The platform includes support for vxHpc terminal emulator software. Further, all of these devices are Windows CE compatible – meaning data and test results can be shared quickly with a PC operating Windows.

The Modules and the Platform
The Tektronix NetTek platform includes the display, power supply, CPU and battery compartments. Measurement modules can then be attached to the back. Up to four modules can be attached at once. A variety of modules and options allows you to tailor the instrument to service the standards and interfaces in use in your network. The modular design also means that the instrument can easily be upgraded. New measurements or standards can be added with software upgrades or with additional modules. The NetTek platform today supports not only the YBT250 test module for spectrum and base station testing, but also the YBA250 module for antenna and transmission line analysis and the YBT1 for T1 testing.

Tektronix YBA250 BTS Antenna And Transmission Line Analyzer

Antenna and Transmission Line Analyzer for Wireless Communications Systems
The Tektronix NetTek Analyzer is a revolutionary portable BTS field tool. The YBA250 test module tailors this system for fast identification of base station antenna and transmission line trouble, and easy location of those faults. The YBA250 test module offers this capability at a surprisingly low price, in a rugged, easy-to-use package, suitable for all field environments.

Return Loss/VSWR
The YBA250 antenna test module allows you to quickly analyze the system using either Return Loss or VSWR. Comparisons against initial conformance tests enable users to easily identify degradation in system performance. Viewing the frequency response vs. channel tables for various standards provides easier interpretation of how the problem may be affecting performance.

Cable Loss
Cable loss can be measured using a simple, single port technique. This makes use of the Cable Loss feature of the YBA250. This feature allows measuring cable loss while connected to only one end of the cable. This is useful when access to the other end of the cable is difficult.

Distance-to-Fault (DTF)
The YBA250 test module helps locate antenna and transmission line faults quickly and easily. Using the Distance-to-Fault (DTF) capability, users are able to identify problem areas and their location. The YBA250's interface provides access to multiple cable types and easier setup of DTF parameters for faster troubleshooting.

CW Mode
The YBAS250 can be used as a sine wave, or continuous wave (CW) source. This is useful for many different trouble shooting applications.

Easy To Use
The NetTek BTS field tool is based around the familiar Windows CE operating system. As a result, users will spend less time learning the instrument and more time troubleshooting the network. The YBA250 test module puts measurement functions just a point of the finger away. Furthermore, built-in help guides speed the measurement process.

Common measurements have been optimized for quick, repeatable results. For example, novice users can display Distance-to-Fault results with straightforward Windows-like zoom and resize controls.

To further minimize troubleshooting time and improve effectiveness, users can control the YBA250's accuracy and resolution to optimize measurement results. For easier interpretation of these results, the YBA250 also enables user-defined masks to qualify antenna performance. This provides faster analysis and allows users to share masks and results.

Insertion Loss and Insertion Gain
System and RF component performance can be easily analyzed with the two port insertion loss or insertion gain capability of the YBA250, when used in combination with a YBT250. This capability allows measurements of cable, connector, and attenuator loss. It also allows measurements of filters, duplexers, RF path gain, amplifiers, antenna isolation, and many other general purpose RF measurements.

The Insertion Loss and/or Insertion Gain capability also allows measurements of Tower Mounted Amplifiers (TMAs, or receiver preamplifiers) while the TMA is still on the tower. Caution: Please check your country's laws regarding transmitters before using the NetTek to transmit a test signal.

Features:

• Improve Quality of Service Through Preventative Maintenance Activities On Antennas, Before They Becom Service-affecting
• Quickly analyze the most important antenna and transmission line problems
• Easy-to-use Distance-to-Fault (DTF) Measurements for locating antenna and transmission line trouble
• Advanced calibration technique speeds and simplifies your measurements by allowing a single calibration for use across entire frquency range

Applications:

• Return Loss/VSWR/Cable loss measurmenets for antenna and transmission line analysis
• Distance-to-Fault (DTF) measurements for locating problems
• Maintenanace and installation checks
• Insertion gain/Insertion loss measurements
