Formulation of the problem. To analyze radio frequency monitoring systems and complexes that can operate in a wide frequency band with high performance parameters, devices such as acousto-optical spectrum analyzers (AOS) are used. This class of devices has several types of implementation. The objective of this article is to increase efficiency in the development of acousto-optoelectronic devices in radio frequency monitoring systems.

Target. Based on theoretical and experimental studies, it is necessary to determine which version of the acousto-optical spectrum analyzer will ensure the operation of radio frequency monitoring tools with the best values of radio frequency characteristics, such as dynamic range and signal-to-noise ratio.

Results. A calculation of the dynamic range of an acousto-optical spectrum analyzer is presented, as well as a comparative analysis of several acousto-optical spectrum analyzers (an acousto-optic spectrum analyzer with time integration and an acousto-optic spectrum analyzer with spatio-temporal integration) to determine the most effective type of device for radio frequency monitoring systems.

Practical significance. The use of the selected design of an acousto-optical spectrum analyzer will make it possible to replace other devices and replace less efficient analogues of the device, which will improve the operation of radio frequency monitoring systems and complexes.
