The object of the project is local oscillator for receivers intended for spectral radio astronomical investigations. Methods and equipment - modern methods of frequency synthesis are used, including direct digital synthesis, frequency conversion, and phase-locked synthesis. Results and scientific novelty – A system of local oscillators intended for frequency conversion of receiving systems of a radio telescope is developed. It has been shown that direct digital synthesizers should be used to provide the required resolution. It is shown that the application of such synthesizers is possible only under conditions of low frequency multiplication, and also with careful filtering of all sources of reference signals.  Product Description popup.authors Alekseev Yevhen A.
