本文介绍一种将锁相式频率合成技术和高稳定度晶体振荡器相结合而构成的三相正弦波信号源.该信号源不但有同晶体振荡器同样高的频率稳定度,而且频率在1～1000Hz间连续可调,满足了科技领域对信号源稳定度与频率宽度的要求.
This paper presents a three-phase sine wave signal source composed of a phase-locked frequency synthesizer and a high-stability crystal oscillator, which not only has the same high frequency stability as the crystal oscillator but also has a frequency of 1 ~ 1000Hz continuously adjustable, to meet the technical field of signal source stability and frequency width requirements.
