About the paper

Abstract

Frequency standards using for VLBI have to be extremely phase and frequency stable for coherence losses minimize. Feature of the new radio telescopes RT-13 of VLBI complex Quasar-KVO is that the recording and data conversion equipment is located in the elevation cabin of radiotelescope. This requires the transmission of a reference signal to a radiotelescope without insertion phase distortion. Different methods of the reference frequency transmission to the radiotelescope are investigated by the Institute of Applied Astronomy. The experimental results of investigated for transmitting reference signals over RF cable and fiber optic cable are presented.
