Ключевые слова: VLBI DAS, BRAS, digital downconverter bank.

Broadband Acquisition System (BRAS) is a digital backend used on new fast-slew rate radiotelescopes RT-13. The system implements eight wideband channels of 512 MHz that allows to achieve high sensitivity of the radio interferometer but complicates processing of joint observations with narrow-band types of backends. To simplify such observations IAA RAS is developing external digital downconverter bank. The results of the development is presented.
