A data acquisition system for test and control of superconducting integrated receivers

A data acquisition system for the Integrated Receiver Test and Control ("IR TECON") was developed and tested with the single-chip quasioptical receiver containing a planar double-dipole antenna SIS mixer and FFO as a local osc illator, The basic system includes a controlling computer with two acquisit ion 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 regime s over the receiver frequency range, The possibility to optimize automatica lly 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 re ceiver on remote location.
