Abstract

The results of tests of a data stream converter based on field programmable gate arrays in actual radio astronomy observations are presented. The observations have been carried out via joint use of radio telescopes, RT-32 with narrowband channels of acquisition and recording and RT-13 with a wideband-signal recording system and a data-stream converter. It has been shown in the tests that the accuracy in measuring the group delay deteriorates compared to the theoretically attainable value; however, the use of the data-stream converter is effective, since it helps to reduce the data stream from the RT-13 radio telescope by eight times and provide the compatibility with RT-32.
