如果你在NI-DSA Set BaseBand or Zoom FFT Settings.vi 中选择一个小于100%的时间增量(时间交叠),并且在设置增量之后立即调用NI-DSA Restart Averaging ,结果在一开始就会错误。一点一点地,它们将接近正确的或预期的平均结果。
原因是 NI-DSA Set BaseBand or Zoom FFT Settings 功能将时间记录归零。如果立刻重新启动后求均值,那后来时间记录将被处理并取平均值。后面的部分为0的记录也将被平均,直到一个完整的记录时间数据准备完毕。然后平均值将或多或少正确的,但它仍然会显示减小的值,因为第一个归零的时间记录也被平均了。
