Abstract

Results of VLBI observations, which have been carried out by "Quasar" network using the usual analog DAS are compared with the new R1002M systems with digital base band converters. Using R1002M system allows to increase the signal-to-noise of fringe amplitude and to raise the accuracy of multi band delay.
