Model correcting device used for communication electronic device simulation test

Abstract

The invention relates to a model correcting device used for communication electronic device simulation test. The device comprises carrier vehicles which are respectively placed at a launching point and a receiving point. The launching point carrier vehicle is provided with a carrier generator and a power amplifier, wherein the carrier generator and the power amplifier are connected through a radio frequency cable. The launching point carrier vehicle is provided with a standard gain antenna I which is connected with the power amplifier through a radio frequency feeder. The receiving point carrier vehicle is provided with a field strength instrument. The receiving point carrier vehicle is provided with a standard gain antenna II which is connected with the field strength instrument through a radio frequency feeder. According to the invention, the carrier generator is used as a radio frequency signal source; a carrier radio frequency signal which is outputted by the carrier generator is amplified by the power amplifier, and is finally transmitted through an antenna; and the carrier generator is used as the radio frequency signal source, which reduces the device cost, improves the smoothness of signal transmission, and can reduce measurement errors.

Description

technical field [0001] The invention relates to a model correction device for simulation test of communication electronic equipment, which mainly solves the problem that the simulation test of communication electronic equipment cannot be carried out normally due to the lack of a special model correction device. Background technique [0002] In the simulation test activities of communication electronic equipment, test results need to be obtained through model calculation and data processing. The accuracy of the model directly affects whether the test results are credible, and model correction is an effective way to improve the accuracy of the model. [0003] When performing model correction, the appropriate test points are firstly selected as transmitting points or receiving points. At present, because our unit does not have a special model correction device, the alternative method adopted is: set up the existing communication signal simulator 1 and its antenna 4 system at th...
