Radio frequency measuring method

Abstract

The invention relates to a radio frequency measuring method, which belongs to a method for measuring a radio frequency element by adopting a radio frequency measuring system consisting of a network analysis instrument, a radio frequency switch and a control computer. According to the radio frequency measuring method, when a network analysis instrument is used for scanning each frequency point of one port of a radio frequency switch, a control computer is used for synchronously reading a measuring value of each frequency point measured in a last port through scanning by the network analysis instrument, and meanwhile, the control computer is used for synchronously processing the data of each frequency point measured in the last port by the network analysis instrument and outputting the data so that the time for the radio frequency measuring system to cyclically measure all ports for once is greatly shortened. The radio frequency measuring method has the advantage that the time for the radio frequency measuring system to cyclically measure all ports for once can be greatly shortened.

Description

technical field [0001] The invention relates to a radio frequency measurement method, which is mainly used in the method of measuring the performance (such as parameters such as reflection coefficient and penetration coefficient) of radio frequency components (such as antenna, filter, amplifier, etc.). Background technique [0002] Radio frequency technology is currently widely used in various radio communication products, including mobile phones, digital TV broadcasting, wireless Internet access, satellite navigation, etc., which have a huge and far-reaching impact on human life. The application of mobile phones shortens the distance between people. Digital TV broadcasting enables people to watch TV at any time, wireless Internet access enables people to send and receive messages anytime and anywhere, and satellite navigation provides drivers with clear road information, making travel more convenient. These applications make human life more convenient. [0003] Any radio co...

[0005] Although the above-mentioned existing radio frequency measurement system can use the radio frequency switch 20 to increase the number of measurement ports, to save the cost of purchasing the network analyzer 10, and achieve the purpose of increasing the test production capacity; but, if figure 2 As shown, due to the processing flow of the above-mentioned existing radio frequency measurement system, when the control computer 30 switches the radio frequency switch 20 to the measurement port P(n), it will sequentially complete the scan including the network analyzer 10 located at the port Each frequency point of the component under test 40 of P(n), the control computer 30 reads the measurement value of each frequency point measured by the network analyzer 10 scanning port P(n), and the control computer 30 processes the network analyzer 10 scanning port After all the action procedures such as the measurement data and output results measured by P(n), switch to another port P(n+1) to continue the due measurement action procedure; therefore, its disadvantage is the overall The measurement processing speed of the system is slow, so that the screen update of the measurement graphics is too slow
