In this study, an optional assembling of a Mössbauer spectrometer based on stand-alone instruments (an Agilent 33521A function generator and an Agilent DSO-X 2002A digital oscilloscope) is presented. The main goal is to identify the possible functional limits of selected instruments used as standard and cheap laboratory equipment in comparison to the special and expensive devices. For communication with the instruments and to perform all measurement tasks, an application was created in the LabVIEW{trade mark, serif} 2013 (National Instruments), a graphical programming environment. In addition to the instruments, the standard ORTEC NIM system was used in the gamma-ray detection part of the system. Development of the control application to accumulate Mössbauer spectra with synchronization of the reference signal generation and detectors signal processing is presented. Despite the fact that the setup of the spectrometer was correct and usable for daily research, some disadvantages were found. The sources of high measurement dead time value were identified mainly in the oscilloscope usage. Possible solutions to additionally increase the performance of the proposed system are discussed in details.
