| 介绍了锁相放大器的一种校准方法.讨论了锁相放大器的相敏特性、满刻度灵敏度和本机噪声、动态储备、动态范围以及时间常数参数的校准实现方法,结合校准系统对典型参数的测量不确定度进行了评定. |
| 英文摘要: |
| In this paper,the calibration method for lock-in amplifier is described.Some realization ways of calibration are discussed,including the phase sensitive detectors characteristics,full-scale sensitivity internal noise,dynamic reserve,dynamic range and time constants.Combining with to the calibration system,the uncertainty of measurement of the typical parameter is evaluated. |
