About the paper


A two-channel broadband noise signal simulator of a radioastronomic receiving device designed to test signal conversion systems is described. Both channels of the broadband signal simulator contain five switchable filters with 512-and 1024-MHz bandwidths and a special unfiltered channel, which allows testing devices that have different input intermediate-frequency bands. The simulator allows determination of parameters and tuning broadband systems of radio telescopes.
