The design of a fast, versatile associative module (AM) increasing the conversion gain of multichannel analyzers (MA) in multiparameter measurements is reported. The design is especially suitable for pulse height spectrum measurements from high counting rate sources as would be found in reactor sample on-line monitoring systems, being able to acquire spectrum data at input rates in excess of 10[sup 5] Hz. Specific characteristics of the instrumentation are as follows: (1) the system's basic structure is implemented by one multichannel analyzer and one associative module, and allows a programmable conversion gain; (2) the basic structure can be expanded vertically and horizontally; the expanded structures keep the original speed of the basic one; (3) to solve the problem of the fast real-time spectrum acquisition speed, fast electronics is used. Electronics is autonomous in the spectrum acquisition, updating and graphical phases, while it is under computer control in both phases of the system's initialization and the transfer of the updated spectrum data from the MA buffer memory unit to the host; and (4) the system is constructed from commercially available components.
