Various broadcasting television system measurement methods are integrated, the data analysis processing capacity is strong, the functional application is rich, and the requirement for convenience of outdoor work can be satisfied through low cost. The portable multifunctional signal measuring instrument for the digital broadcasting television comprises a smallest system module, a DVB signal input and demodulation module, a system power module, a man-machine interaction module, a CA card communication module and a network communication module, wherein the smallest system module is used for operating an Android operation system and comprises a CPU, an internal storage chip, an NAND FLASH and a hardware encryption IC, and the internal storage chip, the NAND FLASH and the hardware encryption IC are respectively connected with the CPU. The DVB signal input and demodulation module, the system power module, the man-machine interaction module, the CA card communication module and the network communication module are connected with the smallest system module, and the internal storage chip is a DDR3 chip or a DDR5 chip.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, in particular to a portable multifunctional digital radio and television signal measuring instrument. Background technique [0002] With the changes of the times, science and technology have developed rapidly, and people have higher and higher requirements for digital broadcasting and television signals. From the black-and-white era of "seeing and hearing" at the beginning to the color era of "seeing and hearing clearly", people today are pursuing "seeing more clearly and hearing more realistically" to satisfy this One requirement is the emerging Digital Video Broadcasting (DVB). In recent years, countries have formulated plans to stop broadcasting analog TV signals for a limited time and fully switch to digital video broadcasting. During the popularization of digital video broadcasting, the problem that must be solved is the receiving and debugging of digital signals. [00...

AI Technical Summary

Problems solved by technology

[0005] The traditional manual debugging method is time-consuming and labor-intensive, and has been eliminated

The common disadvantages of the digital radio and television signal measuring instruments on the market are: single function, simple interface, inconvenient operation, and unhumanized product experience

In this way, no matter in terms of cost or the convenience of going out to work, it is difficult for traditional signal measuring instruments to meet people's requirements
