基于FPGA的多用途信号发生器的设计
Design of multipurpose signal generator based on FPGA
摘要
Abstract
To obtain different modulating and driving signals suiting for optical fiber sensing and optical fiber communication system,a design scheme of the multipurpose signal generator based on FPGA is proposed. In the scheme,the FPGA device is taken as the hardware platform,and the frequency division technology and DDS technology are used to generate the arbitrary low and medium frequency signal,and output a pulse signal,a DDS signal and DC signal at the same time. Both pulse width and repetition frequency of the pulse signal can be regulated by control keys. The minimum pulse width of pulse signal can reach up to 8 ns,the minimun pulse width deviation is less than 0.5 ns,and the repetition frequency is adjusted from 0.05 Hz to 100 MHz. The output frequency range of the DDS signal is 0.058 2 Hz~100 kHz,and the minimum frequency can reach up to 0.058 2 Hz. The experimental results show that all signals generated by the signal generator have good stability and high preci⁃sion,and the generator is suitable for various fields.关键词
