摘要
介绍一种主要用于AT切微机补偿晶体振荡器(MCXO)的开发系统。该开发系统由温控柜、多路开关组、PC机、高分辨力频率计、频率标准、控制系统和基于虚拟仪器的人机界面组成。使用该开发系统生产的微机补偿晶体振荡器在-40℃-85℃的温度范围内,可以获得±1-3×10-7的温度-频率稳定度。
This paper describes a MCXO development system used mainly for MXCOs based on AT cut crystals. This system is composed by a temperature chamber, several switch groups, a PC computer, a high -resolution frequency meter, a frequency standard, a control system including a simulator and a controller, a human interface based on virtual instrument. It can be used to produce the MCXOs with AT cut crystals and in the different temperature range(- 40℃-+ 85℃) ±1 - 3 ×10-7 frequency - temperature stability can be obtained.
