Frequency Hopping Transceiver Tester Display Control Circuit Design And Implementation

HF(Hopping Frequency) communication technologies because of its more secrecy and superior anti-interference capability. Therefore, HF transceiver has been application in military field of many countries.At present, because of technical barriers and research corporations accessed restrictions, HF transceiver testing equipment premature. Because of HF transceiver has been widely used in the military field, so without its sophisticated testing equipment will give the security of our country's military communications hidden danger. In this situation, the author designed a HF transceiver testing equipment's hardware platform.In the first, the article has designed HF transceiver testing equipment's functional blocks of hardware platform. Introduced HF transceiver's main function and its internal functional structure, it let to understand HF transceiver. According to HF transceiver's main function, set HF transceiver testing equipment's function, achieve the function and describe it. Finally, through combination designed functional modules completed HF transceiver testing equipment's hardware platform.After, has completed the display control circuit of HF transceiver testing equipment's hardware platform. According to the designed functional blocks and hardware structure of HF transceiver testing equipment, divided the hardware module to RF front-end, signal process and display control circuits. According to display control block's function, designed and completed the display control circuit and detailed description about it.Finally, has verified HF transceiver testing equipment's functional blocks of display control circuit and hardware platform. According to functional blocks of display control circuit, designed the hardware block's test method, by compared the test results and functional requirements, verified display control circuit. According to completed some test function of HF transceiver testing equipment, verified the hardware platform of testing equipment.This paper designed and completed a HF transceiver testing equipment's hardware platform. The platform supports portable device capability and has powerful signal process ability, can support for more model transceivers testing and no need changing the hardware platform, has certain practical value in engineering.
