Spectrometric complex of RATAN-600. ... There is a system of stable computer driven local oscillators that have accuracy about 10 to degree -8. ... Spectrometer driving system is accomplished with two DVK-4 computers and one IBM PC and make possible to develop radio line observations on the frequency band pass of the input low noise amplifiers ( LNA ): . ... The performance of spectrometric complex is controlled by program driving system ( PDS ) and the data gathering and recording system ( DGS ). ...
