Abstract

The embodiment of the invention discloses a noise figure measurement method, device, equipment and storage medium. The method includes: determining a target measurement channel, the target measurement channel being a measurement channel connected to a device under test; obtaining a target surface mount supernoise ratio of a surface mount noise source configured in the target measurement channel; The mount noise source is a signal source, and the first noise figure of the device under test is determined based on the target surface mount super-noise ratio. The embodiments of the present invention can reduce the testing cost of the device under test by adopting the above technical solution, and realize large-scale testing of the device under test.

Description

Technical field [0001] The present invention relates to the field of measurement, and more particularly to a measurement method, apparatus, device, and storage medium of a noise coefficient. Background technique [0002] With the rapid development of mobile communication technology, the accuracy of the measurement results of the Device Under Test, DUT noise factor is also increasing. [0003] The technical solution of the noise coefficient of the existing measurement to be tested is to connect the device to the noise analyzer (or the spectrum analyzer), respectively, and the standard noise source known in the frequency band, and use Y factor method to measure the measurement The noise coefficient of the device, as in the calibration process, the standard noise source is recorded by noise analyzer in two states of the switch in two states. During the measurement process, the total noise of the standard noise source switch is recorded by the noise analyzer. Power, thus calculate th...
