Abstract
A data acquisition system for the Integrated Receiver Test and Control (IRTECON) was developed and tested with the single-chip quasioptical receiver containing a planar double-dipole antenna SIS mixer and FFO as a local oscillator. The basic system includes a controlling computer with two acquisition cards, an analogue bias supply and GPIB linked peripheries. The system collects and analyzes I-V data of the FFO and SIS mixer, tunes their regimes over the receiver frequency range. The possibility to optimize automatically the receiver noise temperature is realized. This system can be adopted to control a wide range of SIS-based receiving system such as an imaging receiver on remote location.
