ABNORMALITY DETECTING METHOD OF TRANSCEIVER AT BASE STATION AND DEVICE THEREOF

摘要

PURPOSE: A method and a device are provided to detect an abnormality by checking inside a transceiver that makes a wireless base station. CONSTITUTION: The transceiver of the base station comprises the steps of: reading the first minimum value and the first maximum value of a stored receiving input signal level; reading an automatic gain adjusting circuit control voltage that is generated at an automatic gain adjusting control circuit; changing the measured automatic gain adjusting circuit control voltage to the receiving input signal level; and judging that the abnormality of amplifying movement is generated in a receiving frequency changing board if the receiving input signal level is lower than the first minimum value.
