Pulse-height analysis PHA of image intensifier tubes I2 tube is described using a multiple-channel analyzer MCA. The experimental setup, schematics of I2 tubes, statistics and mathematics for the analysis, and methods for data acquisition and reduction are included in the report. PHA complements another experimental technique which measures the noise figure Nf of an I2 tube by explaining causes for good or bad performance of the tube. Technical developments of I2 tubes over the years were retraced to point out the improvements or the distinctions of a later generation I2 tube over an earlier one. Some of the tube characteristics are described in detail when they affect the Nf or the gain noise figure. Background mathematics and statistics are illustrated, and some useful oscilloscope traces are given.
