Multiple tools

Power meter The built-in power meter replaces the need to carry a separate power meter, simplifying

overall maintenance routines and shortening site visits. Additionally, using an

appropriate power sensor enables technicians to make power measurements of

microwave links. Accurate power settings help technicians maximize network capacity

while reducing coverage holes and minimizing the effects of interference.

W-CDMA (UMTS), HSDPA, cdmaOne, Provides fast, qualified measurements in less than five minutes. Enables time for

CDMA2000 1X, and CDMA2000 1xEV-DO proactive maintenance and makes pole top testing practical. Problem areas can be

over-air test tool identified without interrupting service.

CW, cdmaOne, CDMA2000 1X, Provides the technician with a source to conduct sensitivity measurements. Additionally,

CDMA2000 1xEV-DO, and iDEN this option allows a technician to perform component level characterization utilizing

reverse link signal generator simultaneous spectrum analysis and built-in RF and CDMA sources. Reverse link testing

helps to ensure network Rx service quality.

Antenna tester with vector network Lets technicians evaluate one of the primary BTS trouble spots in a matter of minutes.

analysis capability Dual port insertion loss allows technicians to sweep various components like filters,

• cable tests duplexers, amps and more. DTF resolution includes 256, 512, or 1024 data points,

• distance to fault (DTF) enough resolution to locate and isolate faults within a few centimeters (inches) of one

• swept insertion loss another or resolve short jumper cables at the end of a long antenna feed line. A healthy

• swept insertion gain antenna and feed line network yields improved voice quality, better system reliability

and reduced dropped calls.

T1 or E1 Identifies and diagnoses T1 or E1 problems. Dual channel capability allows “loop-back”

measurements. Fewer wireline problems mean reduced service problems and down time.

Spectrum analyzer Provides necessary functionality so technicians don ’t need to carry a separate spectrum

analyzer. Built-in spectrum emissions masks, occupied BW, Spectrogram, and markers

make it easy-to-use. Industry-leading low noise figure receiver is capable of measuring

down to –150 dBm, allowing technicians to identify and pull out low level, intermittent

rogue interferers. Quick interference detection leads to improved quality of service.

Channel scanner for CDMA, W-CDMA Provides easy to interpret bar graph display illustrating channel power versus frequency

(UMTS), cdmaOne, CDMA2000 1X, of user defined channels. The channel scanner quickly identifies improper power levels

CDMA2000 1xEV-DO, TDMA, GSM/EDGE that can adversely affect network performance.

GPRS, AMPS, and iDEN

TX RF modulation analysis for TX modulation testing provides extensive transmitter analysis for various 2 to 3G formats

W-CDMA (UMTS), cdmaOne, like modulation quality (phase error, Rho, EVM), time offset, code domain power and

CDMA2000 1X, CDMA2000 1xEV-DO, display, channel power, etc. In addition, W-CDMA, and CDMA applications include

GSM, and EDGE Codogram analysis.

Internal GPS receiver Provides position location, highly accurate frequency measurements and enables

independent verification of base station GPS receiver timing. For CDMA networks, the

internal GPS receivers help reduce dropped calls by identifying the “island cell”

effect – improving the quality of service.

Interference analysis Allows engineers and technicians to find intermittent, interfering signals using a

• spectrogram display • level meter spectrogram display, signal strength meter and signal ID capability. Eliminating

• modulation ID function interfering signals from the network improves quality of service.
