Example Embodiment

[0050] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0051] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be a central element at the same time. When an element is said to be "connected to" another element, it can be directly connected to the other element or an intermediate element may also be present.

[0052] It should also be noted that the directional terms such as left, right, up and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should not be c...

Abstract

The invention discloses an indoor distribution power test method and device for a mobile communication base station. The device comprises a first switch module, a band-pass filter bank, a second switch module, a first frequency mixing module, a second frequency mixing module, a first local oscillation module, a second local oscillation module, a clock module, an A/D conversion module and an FPGA module. The method disclosed by the invention can control the filter bank to be rapidly switched when different operators and different communication systems are measured, local oscillation output power is configured in real time, a sampling clock at a high sampling rate is adopted for performing high-speed acquisition on data, and then rapid and accurate measurement on in-band power is realized according to different communication systems, so that not only the problem that the traditional measured power is inaccurate is solved, but also the effect that different communication base stations aresent at the same time and are measured at the same time is realized, and the problems of test efficiency and test accuracy are effectively solved.

Description

technical field [0001] The invention relates to the field of indoor distributed testing of base stations, in particular to a method for testing indoor distributed power of mobile communication base stations. Background technique [0002] With the rapid development of communication technology, the coexistence mode of multi-operator and multi-communication standard base stations is becoming more and more popular, especially in the large-scale layout of indoor distribution. The power of the base station under the standard has become an issue that the industry pays more and more attention to. As an important part of communication development, communication test instruments play an irreplaceable role in the test, and base station indoor distributed power test instruments, as an important part of it, play an increasingly important role. [0003] For the measurement of distributed power in the station room, the traditional measurement method is to conduct statistical tests through...
