Cable automatic calibration and automatic compensation method of comprehensive detection equipment

Abstract

The invention relates to a cable automatic calibration and automatic compensation method for comprehensive detection equipment; the method employs an operation terminal, the comprehensive detection equipment, a power meter, a signal generator and a switch to carry out automatic calibration and automatic compensation of a cable. The method comprises the following steps: firstly, obtaining power calibration data of the signal generator, then connecting one end of the cable to an output port of the signal generator, and connecting the other end of the cable with the power meter; and setting parameters required to be calibrated of the cable in a cable automatic calibration function of the operation terminal, selecting measured power calibration data of the signal generator, starting automatic calibration work of the cable, and automatically generating a power compensation value of each frequency point after the cable is calibrated. According to the invention, automatic calibration of a self-defined frequency band can be carried out on any type of cables, corresponding cable compensation files can be stored, and real-time loading of other cable data and modification of cable compensation data can be supported.

Description

technical field [0001] The invention belongs to the technical field of cable calibration and compensation, and in particular relates to a cable automatic calibration and automatic compensation method of comprehensive detection equipment. Background technique [0002] The comprehensive testing equipment is suitable for the testing and maintenance of field radars and radio stations, as well as the development, production, maintenance and testing of electronic equipment. In the actual test process, it is necessary to connect the comprehensive testing equipment with the equipment under test, in which the compensation data accuracy of the connecting cable plays an important role in the accuracy of the final test result, so how to quickly calibrate the cable and obtain more accurate The cable compensation data is particularly critical. Existing comprehensive detection equipment mostly measures the single-point compensation value of the cable based on the test single-frequency poi...
