Abstract

The invention relates to a gain calibration method and device, computer equipment and a storage medium, and the method comprises the steps: enabling calibration equipment to control a frequency sourcein to-be-tested equipment to output a first dot frequency signal with preset power according to a working frequency band of a to-be-tested channel in the to-be-tested equipment, then, detecting an output power value of a second dot frequency signal power detection equipment, wherein the second dot frequency signal is obtained by converting the first dot frequency signal by the to-be-detected channel, and finally, adjusting the gain calibration adjustment value of the to-be-measured channel according to the output power until the output power value is within a preset power range. By adopting the method, the calibration accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a gain calibration method, device, computer equipment and storage medium. Background technique [0002] The Remote Radio Unit (RRU for short) is an important part of a wireless communication base station. It mainly implements the frequency conversion and amplification of the baseband signal and sends it to the terminal device, and receives the RF signal sent by the terminal device, and transmits the RF signal to the terminal device. Handles conversion and transmission to baseband equipment. Before the RRU unit leaves the factory, the gain of the RRU unit needs to be calibrated first, so that the gain of the RRU unit is within a preset range. [0003] In the traditional technology, the calibration system of the RRU unit includes a baseband unit and a power detection device. The baseband signal is sent to the RRU unit through the baseband unit, and then the po...
