幅度响应是多道分析器测量幅度谱时的主要特性之一。通过测量幅度响应可以测定零点、变换系数及其稳定性,还可以测定积分非线性和计数率变化时引起的峰位漂移。本文对目前常用的道边界法和白噪声峰位法作了分析比较,并提出使用低频函数法的可能性。希望引起讨论和研究。 Amplitude response is one of the key features of multichannel analyzer measurement amplitude spectrum. By measuring the amplitude response can be measured zero, transform coefficients and their stability, you can also measure the integral nonlinearity and counting rate changes caused by the peak position drift. This paper analyzes and compares the commonly used method of channel boundary and white noise peak, and proposes the possibility of using low frequency function method. Hope to arouse discussion and research.
