Implementation method for generalization and parallelization of data conversion of vector network analyzer

Abstract

The invention relates to an implementation method for generalization and parallelization of data conversion of a vector network analyzer. By using a virtual function for processing coordinate conversion, the coordinate conversion has uniform processing steps in various graphic formats of the vector network analyzer; if a new graphic format is added, only a new graphic class and a coordinate conversion function thereof are required to be designed, and the integral structure of software is not required to be changed, so that generalization of operation is realized, human intervention for program control is reduced, and the maintainability and the compatibility of the software are greatly improved; the coordinate conversion and graphic drawing are processed in parallel by using multi-thread design; the multiple threads comprise a scanning thread and a drawing thread; and thus, the real-time property of the system is improved.

Description

technical field [0001] The invention relates to the field of vector network analyzers, in particular to a method for realizing generalization and parallelization of data conversion of vector network analyzers. Background technique [0002] With the development of science and technology, the handheld vector network analyzer has become an important development direction of the vector network analyzer. In the handheld vector network analyzer, due to the limitation of volume and power consumption, its calculation speed and memory space cannot Compared with large-scale desktop vector network analyzers, how to reduce the impact of hardware limitations on measurement accuracy and speed, and maximize the performance of the instrument on limited hardware resources, is the development of resident software for handheld vector network analyzers. issues that must be considered. [0003] The scheme of existing data conversion technology is as follows: [0004] Design a mapping table to ...

Problems solved by technology

[0006] First, it is not flexible enough and has low compatibility. Although the existing technology uses a mapping table better than using a switch-case structure, it still belongs to a program structure for artificially controlling the process—it needs to add judgment statements to select the correct coordinate conversion function. , because the vector network analyzer has many graphic formats, and new graphic formats may be added at any time, the implementation method of the current technology is not flexible enough, and the backward compatibility is low

[0007] Second, the real-time performance is low, and the trace drawing is executed sequentially after the coordinate conversion, which takes up the time of data processing
