The goal was to research and write software for a microcontroller for implementing a laboratory model for amplitude modulation, which we use to study the temporal and spectral characteristics of signals with amplitude modulation. During the work, we studied the structure of the functional of the laboratory model, and also studied the blocks connected to the STM32F407VG microcontroller. Further, the program algorithms for managing the system were developed and programs were written for controlling the units of the laboratory setup and the main program for controlling the operation of the device. Work with this microcontroller is carried out in the development environment Keil uvision 5. To verify the operation of the device, testing was performed and the results of studies of the operation of the device are presented. From the first and second connectors of the device we get the signal of the carrier frequency and the modulating frequency. We connect oscilloscopes to these connectors to obtain oscillograms of these signals. From the third connector we get a modulated signal. Using a spectrum analyzer, we obtain spectrograms for various modulation modes: amplitude modulation, balanced modulation with suppressed carrier frequency and single-band modulation with suppressed carrier frequency and upper sideband.
