摘要

在声光可调滤光器（AOTF）近红外光谱仪系统中

稳定的射频驱动信号源是AOTF实现分光功能的关键。本文根据近红外光谱分析所需的波长范围

利用直接数字频率合成（DDS）技术

设计了驱动AOTF所需的射频信号源。系统包括单片机控制模块、DDS信号发生模块、滤波电路、功率放大模块四部分。经实验测试

系统可在80

50 MHz频段内任意频点输出稳定的正弦信号波形

相对误差在0.45%以内

功率为1 W

满足AOTF的工作要求（对应输出波长范围900

700 nm）。

Abstract

Acousto-optic tunable filter（ AOTF） is the fifth generation of spectroscopic system core component. In AOTF near-infrared（ NIR） spectrometer system. Stable RF driven signal source is a key issue in research and development of AOTF NIR Spectrometer system. Based on wavelength range of near infrared spectroscopy

The system uses SCM to drive DDS and designs output frequency range at 80

150 MHz. The system includes a singlechip control module

DDS signal generator module

filter circuit

power amplifier module. Test results show that in the desired output frequency range

the system can output the desired waveform and output signal frequency relative error within 0. 45 %

with power of 1W

corresponding to the output wavelength range of 900

1 700 nm.
