Introduction

Many of modern wireless base stations are a complex system of multiple RF components such as

Low Noise Amplifiers (LNA), duplexers and Tower Mounted amplifiers (TMA). The performance

of those RF components directly affects cell site’s coverage and capacity. It is essential to have the

right instrument to service and verify the proper functionality of those components.
The JD725A has all of necessary measurements functions to perform RF component measure-

ments including, insertion gain, insertion loss, antenna isolation, TMA performance and duplexer

antennas verification.
In addition, the JD725A accurately characterizes the site’s antenna system including Voltage Stand-

ing Wave Ratio (VSWR), Distance To Fault (DTF), cable loss and power measurements.
The JD725A is an easy to use field instrument, equipped with a touch panel color display allow-

ing rapid measurements and obtaining results clearly displayed. Its application software, JDViewer,

allows the user to easily compare and analyze measurements and generate professional reports.
The JD725A was designed for field testing operation and is equipped with a rechargeable field

replaceable Lithium-Ion battery which enables continuous operation for more than three hours.
