A system and method for point detection of line loss

Abstract

A line loss point inspection method, comprising the following steps: adjust the configuration line loss value corresponding to the frequency band through the line loss setting strategy, and perform gold machine production; use the gold machine to perform spot inspection on the environmental line loss; increase the power correction parameters of the frequency band , to eliminate the impact of adjusting the configured line loss value corresponding to the frequency band, and obtain the real power in the spot inspection environment. The present invention also provides a line loss point inspection system, which overcomes the problems of differences between different instruments and measurement accuracy in the prior art, effectively avoids the problem of negative value of small line loss in gold machine point inspection, and improves the production efficiency of the factory. Save the factory and customer production costs.

Description

technical field [0001] The invention relates to the technical field of production calibration of communication data products, in particular to a line loss point inspection system and method for production calibration stations. Background technique [0002] At present, in the production calibration process of communication data products, it is usually necessary to use the corresponding gold machine to perform environmental line damage point inspection before the calibration station is executed, so as to avoid the problem of inaccurate calibration data caused by abnormal environment. [0003] Before the official production, the gold machine of the corresponding model will be produced, and the power value Pa of a fixed PA control word (power control word) is saved in the gold machine flash. Send the control word of the fixed PA that has been stored during the spot check of the gold machine to obtain the power under the spot check environment, and then calculate the environmenta...

Problems solved by technology

[0004] Generally, if the line loss in the point inspection environment is relatively small, due to differences between different instruments and power measurement accuracy problems, the line loss value calculated by the point inspection line loss of the gold machine will be negative.

Usually in this case, it is necessary to replace the radio frequency line with large line loss, redo the gold machine and then re-inspect, which has certain requirements for the factory to use radio frequency line materials, which is inefficient and increases the cost of the factory and the production cost of customers.

Or the line loss detected by the point is within a certain range of negative values ​​(such as within -0.1 to -0.2), and the line loss of the station is directly set to 0, which sacrifices some calibration accuracy

If the environmental line loss is directly set to a negative value for calibration production, it is easy to cause confusion
