Abstract:
An apparatus for measuring air interference of a base station at said base station comprising:an RF (Radio Frequency) switch having inputs to select one path of a plurality of sectors, for setting a measurement path to selectively measure each path and sectora low noise amplifier (LNA) receiving an input signal output from said RF switch and amplifying said signal to be within an effective level and to be read in a spectrum analyzer;a control computer for controlling a decoding unit and said spectrum analyzer as a core of an air interference measurement set (AIMS);the decoding unit generating a decode-output to control said RF switch by receiving data from a parallel port of said control computer; andthe spectrum analyzer automatically performing interference-measurement in a remote state by receiving an output signal of said low noise amplifier (LNA) and then transmitting and receiving data with said control computer through a general purpose interface bus.
