Problems solved by technology

[0004] However, when the existing RF test system is testing the RF energy, due to the influence of the noise figure, when the test system cannot eliminate the influence of the noise figure during the measurement process, the RF frequency curve tested by the test system will appear Error, and the test of the test system at this time will be a meaningless test

Embodiment Construction

[0044] After the applicant's research and analysis, the reason for this problem (inaccurate test data of the existing test system) is that, when the existing RF test system is testing the RF energy, due to the influence of the noise figure, the test system is in the When the influence brought by the noise figure cannot be eliminated in the measurement process, errors will appear in the RF frequency curve tested by the test system, and at this time, the test of the test system will be a meaningless test. The present invention is designed to correct the applied energy The correction module reduces the noise-to-noise ratio through the image suppression of the correction module, thereby reducing the error range of the test system and making the test value more accurate. At the same time, the display module is designed to display the measured value curve, and then give the tester The visual and intuitive impact makes it easier to identify the range of measured values.

Abstract

The invention discloses a radio frequency test system and a test method thereof. The radio frequency test system comprises a radio frequency generation module for providing frequency and energy; a radio frequency matching module used for ensuring the stability of applied energy; a correction module used for correcting the applied energy; a radio frequency test module used for testing output energy; and a display module used for displaying an output energy curve. According to the invention, the correction module for correcting the applied energy is designed; the signal-to-noise ratio is reducedthrough image rejection of the correction module, so that the error range of the test system during test is reduced, the test numerical value is more accurate, meanwhile, the display module is designed to display a measured numerical value curve, visual impact of a tester is given, and the range of the measured numerical value is easier to identify.

Description

technical field [0001] The invention relates to a test system, in particular to a radio frequency test system and a test method thereof. Background technique [0002] Radio frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can be radiated into space, and the frequency range is from 300kHz to 300GHz. Radio frequency is radio frequency current, referred to as RF, which is an abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that changes more than 10,000 times is called high-frequency current, and radio frequency is such a high-frequency current. [0003] Radio frequency (300K-300G) is a higher frequency band of high frequency (greater than 10K), and microwave frequency band (300M-300G) is a higher frequency band of radio frequency. [0004] However, when the existing RF test system is testing th...
