摘要
简要介绍了数字式记录仪的特点并推导了将其用于冲击测量时对其基本参数的要求。建议用于高压冲击测量的数字式记录仪,其分辨率不应小于8位,采样频率不应小于60MHz,同时它的微分非线性及积分非线性等亦须满足IEC国际标准1083-1的要求。具有这样特性的数字仪才能满足GB 311.4-83或IEC 60-3-76对高压冲击测量的要求。
The basical features of digital recorder are introduced and the main parameters of digital recorder for high voltage impulse test are derived. It is suggested that the resolution and the sampling rate of digital recorder for high voltage impulse test should not be less than 8 bit and 60MHz respectively. It should also satisfy the requirements specisfied in IEC International Standard 1083-1. Only of a digital recorder with these specifications is used in high voltage test the measurement accuracy required in GB311.4-83 or IEC International Standard 60-3-76 can be reached.
