任意波形发生器测量标准不确定度评定

Evaluation of uncertainty for metrological standard of arbitrary waveform generator

任意波形发生器不但可以输出标准信号,而且可以方便地产生复杂波形,以满足人们的需要。任意波形发生器各项参数是否准确直接影响到科研生产及企业的产品质量,因此需要对其各参数进行校准,而校准结果的质量直接关系到其量值传递准确与否,所以需要对其测量标准的测量能力进行评定,以确定校准装置是否满足校准要求。本文对任意波形发生器测量标准不确定度进行了分析评定。评定过程及结论可应用在计量标准进行相关特性的不确定度分析评定上。

Arbltrary Wave.form Generator can satisfy people＇s demand, because it can produce not only standant signals but also complicated signals expediently.However, whether the parameters of Arbitrary Waveform Generator are accurate or not is important for product quality and applicatlon,each of the parameters should be calibrated.This paper discussed unoertainty evaluation of the measurements.The process and conclusion of the evaluation can be applied to the evahation of uncertainty of relative specification of metrological standard.
