一种新的选频电平表平衡输入端口电平测量准确度的校准方法

A new method to calibrate the accuracy of the balanced input level measurement of a selective level meter

文章提出了在不使用电平振荡器和标准零电平表校准选频电平表平衡输入电平测量准确度的新方法,对给出的新方法进行了不确定度评定,并将此方法应用于国家计量技术规范《选频电平表校准规范》中。

In this paper, a new method to calibrate the accuracy of thebalanced input level measurement of a selective level meter withoutusing level oscillator and standard zero level meter is proposed, and theuncertainty of the new method is evaluated, The new method will beapplied to the latest national metrological technical standard CalibrationSpecification of Selection level Meter.
