Systems of recorders and analyzers of high-energy plasma flows intended for operation in low Earth orbit have clearly defined requirements, but their implementation significantly depends on scientific tasks and the project budget. Instead, the requirements for spectrometric channels in terms of radio physics still need to be interpreted in terms of radio engineering, which requires additional research efforts. It is also often necessary to develop parts of equipment without interaction with other contractors and in the absence of access to control equipment or funds for its comprehensive testing. Therefore, a decision was made to develop an option to replace part of the high-cost equipment with the cheapest possible simulator, which will help save time and money when testing and adjusting the payload. An urgent problem is the scaling of the number of simulated spectrometric channels using one available in stock general purpose microprocessor, because the output signal must be analog, and the number of digital-to-analog converters is usually limited to two. The charged particle detectors simulator is intended for testing the DSP module of the miniature recorder-analyzer which is planned to be launched into Earth orbit and developed within of the same study. It should perform discretization of the data obtained by a detector system consisting of paraterphenyl and a large-area photodiode, prepared for discretization by a previously developed analog signal processing module. The output data to be sent to the ground control panel of the miniature recorder-analyzer are: the number of charged particles in accordance with the range of energy carried by the charged particle during the allocated time period. This period of time was decided to be equal to one rotation of a nanosatellite around the Earth. The study was conducted to study the nature of microbursts of sub-relativistic electrons and protons of magnetosphere origin in the Earth's radiation belts.
