Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] At present, the calibration of the automatic test system channel is mainly realized by coding or platforming. Their principles are basically the same. They are all based on the attenuation value generated by the radio frequency signal in the channel transmission as the data source, and calculated in a certain way. Channel errors, and finally compensation for stimulus signals or measurement results during testing.

[0035] The invention proposes a virtua...

Abstract

The invention provides a radio-frequency signal calibration method based on virtual channels, comprising a channel modeling module, a channel calibration module, an error correction module and an information management module. First, the channel modeling module is run to establish a virtual channel model for channels ready for calibration, and channel model information is synchronized to the information management module; the channel calibration module is run to calibrate all the channels; a calibration program generating guide is provided for a user according to the channel model information; a calibration program generated by the guide is run to obtain calibration data, and the calibration data is synchronized to the information management module; then, the error correction module is run; and finally, an error correction algorithm interface function is called during running of a test program to obtain a radio-frequency signal compensation value at a specified frequency of a specified channel to compensate channel calibration error in the process of testing. All the modules have clear functions, operation is simple and convenient, channel management and error correction are completely open, and the channel calibration needs of a test system in different stages are met through extension.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method for calibrating a radio frequency signal based on a virtual channel. Background technique [0002] In the automatic test system, the RF input and output signals have to pass through a series of channels composed of connecting cables, switches and adapters, and the channel error will be the main source of the test error of the entire automatic test system. The channel calibration technology can effectively compensate the attenuation of the RF input and output signals during the transmission process, reduce the errors caused by the system's own factors, and improve the accuracy and reliability of the test. [0003] At present, there are no relevant verification regulations and calibration specifications for automatic test system channel calibration in China. Therefore, the channel calibration methods adopted by many automatic test systems are designed for the specific chan...
