摘　　要：在数字示波器(DSO)技术资料中常见到这样的公式记录长度=采样速率×扫速×10。但对这个公式的来源和意义却未能进行较详细的解说,缺乏深入的认识。文中对这个公式进行了讨论,并指出现代DSO增长记录长度(即增加存储深度)的实际意义。In the technical datum, it is commonly to note a formula as: recorder length=sampling rate×scan speed×10. Nevertheless, it cannot give a particular definition of the origin and meaning of the formula as well as a deeply understand. In this paper, the formula is discussed and the meaning of increasing recorder length of DSO (means increasing of memory depth) is made clear.

关 键 词：数字示波器 记录长度 采样速率 技术资料 实际意义 存储深度 公式 DSO
