Apparatus and method for measuring air interference of a base station

摘要

Apparatus and method for measuring air interference of base station is disclosed. The apparatus for measuring air interference of base station includes RF (Radio Frequency) switch setting measurement path to selectively measure each path and sector, which is outputted from the base station. A low noise amplifier (LNA) receives the signal output from the RF switch and amplifies the signal to be within an effective level to be read in a spectrum analyzer. A control computer controls the decoding unit and spectrum analyzer as a core of the air interference measurement set (AIMS). The decoding unit generates a decode-output to control the RF switch by receiving data from parallel port of the control computer, and the spectrum analyzer automatically performs interference-measurement in a remote state by receiving the output signal of the low noise amplifier (LNA) and then transmitting and receiving data with the control computer through general purpose interface bus.
