Abstract

The invention discloses an X-frequency-band noise coefficient automatic test system with a LAN interface. The system is used for automatically testing the noise coefficient of a receiving module and comprises a spectrum analyzer, a noise source, a computer, a router and a network cable. The spectrum analyzer is connected with the output end of the receiving module, the noise source is connected with the input end of the receiving module, the LAN interface of the computer and the LAN interface of the spectrum analyzer are connected to the same LAN through the network cable and the router, and the noise source provides drive signals for the receiving module. The invention further provides an X-frequency-band noise coefficient automatic test method with the LAN interface. According to the X-frequency-band noise coefficient automatic test system and method with the LAN interface, the noise coefficient of the receiving module can be automatically tested rapidly, accurately and conveniently, noise coefficients of any multi-port network can be automatically tested, universality is high, and the application range is wide.

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.

[0004] The receiving module under test working in the X-band needs to measure dozens of frequency points in total. Each frequency point needs t...
