Abstract: | A new Data Acquisition and Control System for performing continuum radio-astronomical observations with the RATAN-600 radio
telescope is presented. One of the “building blocks” of the system is the Embedded Radiometric Data Acquisition System (ER-DAS)
developed at the RATAN-600. It is a measurement facility meant for digitizing and reducing radiometer signals and for transmitting
the result of these operations via Ethernet networks. ER-DAS system is shown to have a low self-noise level and to lack 1/f-type noise. The measurement facility is shown to operate efficiently in radio-astronomical observations. Radiometric measurements
of the parameters of high-sensitivity radiometers are illustrated in the case of the measurements of radiometer gain fluctuations. |
