Background

With the development of radio technology, more and more specialized radio measurement devices are emerging. The plurality of radio measurement devices can display the waveform of the acquired radio signal and the basic parameter information in real time, but cannot process and analyze the data immediately after the test is completed. The tester needs to extract the data from the measuring equipment to the computer for data processing to obtain the test result. When the large-scale crowd carries out radio measurement tasks, the process of data analysis needs to spend a large amount of time, and measurement results are obtained untimely, so that the field of measurement personnel cannot know the testing quality.

The radio measurement device mainly comprises a spectrum analyzer for measuring signals of various frequency bands; an electromagnetic field intensity meter which can measure the radiation intensity of the electromagnetic field; a radio frequency power meter for measuring the power of the signal. However, the data collected by these devices are often stored in a usb disk inside or outside the system, and we need to clean the past data at random, and release the memory space, which is complicated. Based on the method, the measured data is uploaded to the server, the local data is deleted, the storage space is released, normal operation of the equipment is ensured, and the working efficiency is improved.

At present, professional radio measurement equipment has good comprehensive performance, but the equipment is expensive, the modification of a measurement equipment operating system is poor, and the system cannot be changed as required. Therefore, in homemade portable electromagnetic spectrum measuring equipment, besides the basic radio measurement function, the self-made portable electromagnetic spectrum measuring equipment is innovatively added into a data processing system, and a test result can be obtained without transplanting data after the test is finished.
