A multifunctional digital converter for radio-astronomy signals with a bandwidth of up to 512 MHz

Abstract

A multifunctional digital signal converter is described, which is used as a channel for the digital conversion and formatting of radio-interferometric signals with bandwidths of up to 512 MHz. The converter allows changes in its function by only a change in the control program, which is administered by the radio-telescope computer. The multifunctional computer can be used for radiometric and spectral measurements and for tests of the receiving–amplifying equipment of the radio telescope.
