Intorduction

The GC7106A – RF Analyzer is the ideal solution for installation and maintenance of modern cell sites, combining the functionality of spectrum analysis, interference analysis, cable and antenna analysis, and power measurements.

The GC7106A offers the full scope of common RF performance measurements such as channel power, adjacent channel power, occupied bandwidth, return loss, tower mounted amplifier’s gain and distance to fault location. In addition, the GC7106A provides an Interference Analysis function which presents a spectrogram that shows RF activity through time, detailing differences in frequency and spectral power, identifying unwanted interference by other sources.

Key Measurements

• Spectrum Analyzer

• Interference Analyzer

• Antenna & Cable Analyzer

• Power Measurement

Spectrum Analyzer

The RF Analyzer has a general purposed spectrum analyzer which is the most flexible test tool for RF analysis. Beyond this basic spectrum analysis functionality, a built in RF measurement application provides a single button RF power measurements including:

• Channel Power

• Adjacent Channel Power

• Spectrum Emission Mask

• Occupied Bandwidth

Interference Analyzer

The RF Analyzer has an interference analyzer which is the most effective way to identify periodic or intermittent interference.

A spectrogram display allows the user to capture spectrum activity while displaying frequency, power and time information.

The signal tracking capability is particularly useful for observing signal strength at a single frequency over time with an audible indication.

Cable and Antenna Analyzer

The RF Analyzer can perform also the function of an antenna and cable analyzer that measures cable loss, distance to fault (DTF) and voltage standing wave ratio (VSWR).

The antenna and cable analysis functionality can characterize active and passive devices such as cables, filters, amplifiers, antennas and multiplexers. It also performs gain measurements, insertion loss, and isolation; particularly useful for filters, amplifiers, Tower Mounted Amplifiers (TMA), RF path gain, and antenna isolation.

Power Meter

The RF Analyzer can perform two power testing methodologies:

• Internal, for standard power measurements without the assistance of external power sensors.

• External, for high accuracy power measurements with the assistance of external power sensors.

The internal power meter, with no additional power sensors, uses the spectrum analyzer functionality. It is a simple test methodology with reasonable accuracy. On the other hand, external power sensors perform power measurements more accurately. The RF Analyzer can be equipped with a Directional Power Sensor (through-line) which has the advantage to minimize service disruption and covers an ultra-wide power range.
