Transactions of IAA RAS, issue 45, 109–119 (2018)

Keywords: VLBI, observations, group delay measurement accuracy, data acquisition system.

Abstract

We investigated the accuracy of measuring the group delay in VLBI observations with narrowband, broadband or combine registration. The results of experimental VLBI observations confirmed the possibility of interfacing broadband and narrowband Data Acquisition Systems using the developed Digital Down Converters module.
