Line loss point detection system and method

Abstract

The invention relates to a line loss point detection method. The method includes the following steps of adjusting a configured line loss value corresponding to a frequency band by means of a line losssetting strategy and manufacturing a gold piece; using the gold piece for performing point detection on environmental line loss; increasing power correction parameters of the frequency band, eliminating influences caused by the configured line loss value corresponding to the adjusted frequency band, and obtaining the real power in a point detection environment. The invention also provides a lineloss point detection system. The defects that there are differences remaining in different instruments and the measurement precision in the prior art is low are overcome, the problem that the small line loss value of the gold piece during point detection is negative is effectively avoided, the production efficiency of a factory is improved, and the production cost is saved for the factory and customers.

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
