A METHODOLOGY TO REPRODUCE SLOW OPERATIVE TEMPERATURE TRANSITIONS AND TO MEASURE THEIR INDUCED EFFECTS ON RECEIVERS FOR RADIO ASTRONOMICAL APPLICATIONS

Federico Perini, Fabio Ghelfi
Abstract:
A methodology to reproduce slow variations of operative temperature of electronic devices, and to measure the induced effects on them, is presented. That method has been conceived in order to test and characterise the new receivers developed for the Italian SKA (Square Kilometre Array) demonstrator, based on the re-instrumentation of part of the Northern Cross radio telescope, located in Medicina (Italy). All the instruments of the measurement system are controlled by a PC (i.e. initialization, calibration and data acquisition). This way has been possible to obtain a new thermal characterization method of electronic devices, complementary to the most common one, where the devices are measured at different, but steady, operative temperatures.
