Abstract

The Aldo Paraboni Payload on the Alphasat satellite consists of two Q/V-band transponders and two beacons at Ka- and Q-band. During the first period of experimentation the satellite transponders were set up in loopback mode. By comparison of the Q-band beacon with the Q/V-band transponder loop, the instantaneous frequency scaling between Q and V-band can be determined. In the present paper, the setup of the experiment and processing of the data is illustrated along with measurement results. Furthermore, these results are compared with the frequency scaling model described in the ITU-R P.618-11 recommendation.
