Based on the difference of measuring errors between spectrum and a single pulse, the article introduces a procedure which can improve the specification of non-linearity of commercial ADC for spectrum measurement without channel-width-everaging circuit.

• 摘要根据放射性能谱测量的误差并不等于对单个脉冲测量的误差的特点，提出一种先测出模数变换器的道宽，然后利用软件方法进行道宽均匀的技术。
