| 中文摘要: |
| 数字示波器带宽的提高,导致高频效应影响更加显著,使用条件更加苛刻,对检定设备及其系统连接提出了更高要求.如何减小或消除不良影响及充分挖掘检定设备潜力,实现准确和尽可能全面的检定,本文在依据常规数字示波器检定项目和方法的基础上,研究了各检定项目的可行性及采取的措施,特别是对其带宽和瞬态等高频特性的检定进行了重点讨论,从而实现宽带数字示波器的全面检定. |
| 英文摘要: |
| With the continuous improvement of the band of digital oscilloscopes,the wide bandwidth digital oscilloscopes are affected by high frequency effect more apparent and must be used more carefully,which puts forward stricter requirement about verification equipment and connections between different units. How to reduce or eliminate the bad effects and fully excavate the potential of the verification equipment,in order to realize accurate and entire verification to the greatest extent on the basis of normal verification items and methods of digital oscilloscopes,the paper studies the possibility of these items and adopted measures,especially discusses in detail the verification of high frequency characteristics about their bandwidth and transient response,so the complete verification of wide band digital oscilloscopes is realized. |
