| 摘 要： | 在基于单片压控振荡器MAX038芯片以及闭环控制思想指导下,设计并制作了一种宽频带、高精度、高稳定性的信号发生器,并给出了系统组成及关键单元的设计。实验结果显示：该函数信号发生器能产生7Hz～1MHz的正弦波、方波及三角波等信号,波形精度高、稳定性好,与理论设计相吻合,其性能明显优于开环控制的信号发生器。

| Abstract: | Under the instruction of ideology based on single chip＇ s pressure controlling oscillator of MAX038 chip and closed loop, designed and processed a signal generator with wide frequency range, higher precision and stabilization and promoted design of system composition and key unit. The experiment revealed that the function signal generator could generate signals of 7 Hz- 1MHz sine, square wave and triangular wave with high precision and steady that inosculate with theoretical design, whose properties are transparently superior to the signal generator controlled by open loop. |
