在核武器发展和能源试验计划中常常需要测量记录极短暂的瞬变信号(例如10~-秒)。测量记录单次瞬变信号的传统方法多半是将探头来的模拟信号用示波器显示并拍照记录。但是,要记录这样短暂的电信号对示波器的写速和胶片的灵敏度要求极高,特别在野外现场条件下不易实现。 近年来,数字化记录手段迅速发展,利用计算机采集与处理数据,能够快速自动地提供测试结果。对慢瞬变信号实现数字记录是较容易的,然而对于高速瞬变信号来说, It is often necessary to measure and record very transient transients (eg, 10 to-seconds) in nuclear weapons development and energy pilot programs. Most of the traditional methods of measuring a single transient signal are to display the probe’s analog signal with an oscilloscope and take a picture of it. However, to record such a short electrical signal on the oscilloscope write speed and film sensitivity is extremely demanding, especially in field conditions difficult to achieve. In recent years, the rapid development of digital means of recording, the use of computers to collect and process data, can quickly and automatically provide test results. Digital recording of slow transients is easier, but for high-speed transients,
