A front - end data acquisition system based on STD BUS for Mossbauer spectroscopy is described. The system operates in both pulse height analysis and multichannel scaling mode and allows data pre -processing or filtering. With the system
many kinds of computer and / or microcomputer can easily read out Mossbauer experimental data on real time via a standard interface. The opening structure of the STD BUS managed by a Z80 processor helps to build up a flexible and expansible data acquisition system.
