Abstract
The accuracy of a multi-channel pulse height analyzer (M. C. P. H. A.) rests on its component parts concerning their characteristics, among which the linearity of A-D conversion, the stability of digital computer, the linearity of linear amplifier and the linearity of D-A conversion are important, the first two in particular because of large influences they have on the over-all characteristics of the M. C. P. H. A., especially on the linearity and resolving time with respect to radiation energy, the durable stability of channels, the dead time and the number of available channels. The 100 channel pulse height analyzer and 400 channel pulse height analyzer reported in the previous paper were examined for these characteristics. The result assures their practicability.
