PORTABLE SPECTRUM ANALYZER CAPABLE OF MEASURING THE ELECTRIC FIELD INTENSITY OF A FREQUENCY SIGNAL WHICH IS OUTPUTTED IN THE RELAY OF A WIRELESS NETWORK

摘要

PURPOSE: A portable spectrum analyzer is provided to widely extend the measurement range of electric field intensity by measuring the level of noise and the level of a frequency signal.;CONSTITUTION: A connection unit(31) is connected to an external device. A receiver receives a frequency signal which is outputted from a relay. A measuring unit(28) measures the electric field intensity of the frequency signal. A graphic image corresponding to the electric field intensity, which is measured, is created. The graphic image is indicated in the screen of the external device. The connection unit controls the measuring unit. An attenuator is included in the measuring unit and is controlled by a controller in order to measure the level of noise and the level of the frequency signal.;COPYRIGHT KIPO 2012
