Description

technical field [0001] The invention relates to the field of noise figure automatic test, in particular to an automatic test system and method for measuring noise figure with large amount of data. [0002] Background technique [0003] Noise figure is an important parameter of amplifiers and receivers. The level of noise figure directly affects the sensitivity of the receiving system. It is generally required to be tested in all communication systems to facilitate system performance analysis. For occasions with a small number of occasions, manual measurement can generally be used, and the measurement results are read and recorded manually. However, for applications with a large amount of data, the traditional manual measurement method will seriously affect the efficiency and data accuracy, and is not convenient. Later data calls.

For occasions with a small number of occasions, manual measurement can generally be used, and the measurement results are read and recorded manually. However, for applications with a large amount of data, the traditional manual measurement method will seriously affect the efficiency and data accuracy, and is not convenient. late data call

[0004] The receiving module under test working in the X-band needs to measure dozens of frequency points in total. Each frequency point needs to record information such as noise figure, gain, and test time. The amount of measurement data is large. Manually measure and record the above data of a receiving module takes longer

[0005] For example, TR (Transmitter and Receiver) components in active phased array radar range from a few hundred to tens of thousands. If the traditional manual testing method is used, the testing speed is slow, the efficiency is low, the measurement accuracy is poor, the instrument is easily damaged, and the measurement cost High, so it is necessary to establish an automatic test system to achieve accurate, fast and convenient testing of the noise figure of a large number of receiving modules. Processing speed and accuracy, reducing design costs, etc. are of practical significance
