Abstract
A low cost and simple configuration of multifunctional MCA based on a personal computer is described. It can be used as a spectrum multiscaling analyzer, multi-input pulse height analyzer and dual parameter MCA. It can also be used in a master-slave ADC configuration in order to cut down the dead time of the system. All the functions can be performed by loading the corresponding programs without altering the hardware configuration. Interrupt service routines are used to handle the digital data converted by ADC. A dead time counter is also provided to record the dead time profile by measuring the ADC busy time. © 1992 Akadémiai Kiadó.
