Abstract (EN): A very low-cost portable Multichannel Analyzer (MCA) built with off-the-shelf commercial components is presented. Built around an universal microcontroller based platform for portable instruments, previously developed in our group, this intelligent portable MCA is operated by multicell Li-ion batteries and has power and memory autonomy, for several hours of spectra collecting. The MCA integrates a basic front-end pulse shape amplifier, a base line restorer, a peak detector and logic control circuitry. The growing of the radiation spectrum can be easily observed on site through a dot-matrix graphic display. To save the acquired data and allow for the configuration of setup parameters, it connects to any host computer through standard USB, IrDA or RS-232 serial interfaces being also prepared to interface a GPS unit. Software application programs in both the portable MCA and the host PC are presented.
