概述为捕捉和记录瞬态信号而研制了7027数字式瞬态信号记录仪(以下简称为7027)。瞬态冲击信号具有持续时间短、随机和无规律的特点。在过去,一般用磁带机记录这种信号,事后进行分析处理。随着数字技术的发展和电子计算机的广泛使用。这种模拟记录方法的缺点就逐步暴露出来了。为捕捉信号要用去许多磁带,记下了许多无用的信号;事 Overview The 7027 digital transient signal recorder (hereinafter referred to as 7027) was developed to capture and record transient signals. Transient impact signal with short duration, random and irregular characteristics. In the past, this signal was recorded by a tape drive and analyzed afterwards. With the development of digital technology and the widespread use of electronic computers. The shortcomings of this analog recording method gradually revealed. Many tapes were used to capture the signal and many unwanted signals were recorded;
