Abstract

Local oscillators with wide range of the output frequencies (from 21.5 GHz to 27 GHz) and adjustment step of 400 kHz have been created by the IAA RAS in order to upgrade the receiving system of the RT-13 radio telescopes. Such local oscillator setup requires a large number of similar measurements necessary to identify and eliminate unwanted effects that lead to characteristics mismatch with specified parameters. An automated measurement system is developed to check the compliance with specifications. The system consists of the client-server application, measurement equipment and the interface converter to control the oscillator. Analysis of the generated files with measurement results allows for finding the problems and correcting them quickly, thus achieving compliance of the parameters of heterodynes with the required values in the entire operating frequency range. This paper describes the developed system and shows that it simplifies significantly and speeds up tuning and testing the local oscillators.

21.5 GHz to 27 GHz) and adjustment step of 400 kHz have been created
by the IAA RAS in order to upgrade the receiving system of the RT-13
radio telescopes. Such local oscillator setup requires a large number
of similar measurements necessary to identify and eliminate unwanted
effects that lead to characteristics mismatch with specified
parameters. An automated measurement system is developed to check the
compliance with specifications. The system consists of the client-
server application, measurement equipment and the interface converter
to control the oscillator. Analysis of the generated files with
measurement results allows for finding the problems and correcting
them quickly, thus achieving compliance of the parameters of
heterodynes with the required values in the entire operating
frequency range.  This paper describes the developed system and shows
that it simplifies significantly and speeds up tuning and testing the
local oscillators.
