摘要： The present invention discloses a local oscillator feedthrough signal correction apparatus, including a microprocessor control unit, a first digital-to-analog converter, a second digital-to-analog converter, a mixer, a local oscillator, a signal output line, a signal splitter, and a detector tube. The signal splitter is disposed in the signal output line, and the first digital-to-analog converter and the second digital-to-analog converter are configured to provide the mixer with quadrature direct current components VI and VQ used for local oscillator feedthrough signal correction. The local oscillator provides the mixer with a local oscillator signal, and the mixer outputs a local oscillator feedthrough signal to the signal output line. The signal splitter obtains the local oscillator feedthrough signal by means of splitting, and the detector tube detects the local oscillator feedthrough signal. When a detection value of the local oscillator feedthrough signal exceeds a preset target value, the microprocessor control unit controls and adjusts output values of the VI and the VQ. According to the apparatus provided in embodiments of the present invention, direct current components of quadrature signals I/Q at an input end of the mixer can be adjusted in real time, thereby reducing local oscillator feedthrough.

摘要： Embodiments of the present invention relate to an alarm method and apparatus. The method is specifically: acquiring a first receive power of an active unit and a second receive power of a standby unit; calculating a power difference between the first receive power and the second receive power; and triggering an alarm for the standby unit when the power difference is a positive value and not less than a first threshold, or triggering an alarm for the active unit when the power difference is a negative value and not greater than a second threshold. Therefore, a unit for which an alarm needs to be triggered in a network element is determined by using a power comparing method, and an alarm is triggered for the unit, so that a faulty network element can be checked and processed in advance, implementing high timeliness and excellent real-time performance.
