Abstract

The embodiment of the invention discloses a noise coefficient measurement method, a noise coefficient measurement apparatus, a noise coefficient measurement device and a storage medium. The method comprises the following steps: determining a target measurement channel, wherein the target measurement channel is a measurement channel connected with a to-be-connected device; acquiring target surfacemounting excess noise ratio of a surface mounting noise source allocated in the target measurement channel; and taking the surface mounting noise source as a signal source, and determining a first noise coefficient of the to-be-measured device based on the target surface mounting excess noise ratio. In the embodiment of the invention, by using the method, the apparatus, the device and the storagemedium provided by the technical scheme above, measurement cost of the to-be-measured device can be reduced, and large-scale measurement for the to-be-measured device can be realized.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a noise figure measurement method, device, equipment and storage medium. Background technique [0002] With the rapid development of mobile communication technology, the accuracy of the measurement result of the noise figure of a device under test (DUT) is also increasingly required. [0003] The existing technical solution for measuring the noise figure of the device under test is to connect the device under test with a noise analyzer (or spectrum analyzer) and a standard noise source with known super-noise ratio in the frequency band, and use the Y factor method to measure the noise figure of the device under test. The noise figure of the device, such as during the calibration process, record the noise power of the standard noise source under the two states of switching through the noise analyzer, and during the measurement process, record the total noise of the standard n...
