SPECIALISED STAND FOR MEASURING PARAMETERS OF ADAPTIVE CONTROL CHANNELS

Background. In the development of the space industry, an important aspect is to reduce the cost and time, as well as improve the quality of measurements of the parameters of electronic equipment. Including products that combine both analog and digital units, which include adaptive control channels. To reproduce the properties of radiation of outer space, modeling and simulating installations are used, which is associated with the complexity of the infrastructure of measuring stands, high cost and duration of measurements, difficulties with unsatisfactory test results. The purpose of the presented study is to develop a specialized stand for measuring the parameters of adaptive control channels based on a digital model of the sample under study, reproducing the effects of ECB associated with the impact of cosmic rays using software and hardware methods to assess the stability of adaptive control systems under controlled conditions. Materials and methods. The work is based on the integration of hardware and software components. The hardware part includes a system for introducing and tracking changes in the parameters of analog and digital signals operating in the test sample by means of high-precision ADCs and microcontrollers providing synchronous control of the parameters. A thermal chamber is used as a source of temperature effects close to the conditions of outer space. The software part is implemented on a PC as a module for controlling the stand, which includes: a controlled source of the measured physical quantity; a system for introducing and tracking changes in the parameters of analog and digital signals operating in the test sample; additional measuring equipment that can be included in the measuring stand at the request of the tester. Results. The theoretical basis of the stand has been formed, namely: the purpose, technical capabilities, structure of the hardware and software complex and a detailed description of its components. Conclusion. The developed stand ensures safe, flexible and comprehensive measurement of the parameters of electronic products, the methods currently used to improve reliability, quality, reduce the cost and duration of measurements. Its implementation accelerates the development of reliable systems for space vehicles.
