一种便携式可遥控信号发生器的设计

A Design of Portable Remote Control Signal Generator

信号发生器是电子测量领域内的重要仪器,提供电子线路校试或系统联调时所需的各种制式信号,根据外场试验的应用背景,本文研制了一款便携式可遥控信号发生器。该信号发生器能产生覆盖短波、超短波的定频、跳频信号,最大输出功率可达到15d Bm,特别是该仪器具有体积小、重量轻、功耗低等优点,并可采用无线远程遥控的方式实现对仪器相关设置,同时使用外置的14.4V/10AH锂电池可满足仪器连续工作时间超过4小时,十分适合充当野外各种试验的信号源。

Signal generator is an important instrument in electronic measurement field, which provides various types of signal electronic circuit calibration or systematic test required, according to the application background of field tests, this paper developed a portable remote control signal generator. The signal generator can generate coverage shortwave, ultrashort wave signal, including fixed and hopped frequency, the maximum output power can reach 15dBm, especially, the instrument has the advantages of small volume, light weight and low power consumption, the instrument can be set by using wireless transmission module, and the continuous working time can be more than 4 hours by using an external 14.4V/10AH lithium battery, it is very suitable for signal source of various field tests.
