Abstract
Purpose of this note is to characterise the behaviour of the calibrator named ‘RCA SKY
LOAD’(RCA-SL); the specific feature to investigate is the equivalent temperature seen by the feed.
To do this, it needs both a radio-frequency and a thermal analysis, being the specific emissivity and
the physical temperature of the load strictly tied. Only a combined unitary analysis can allow to
maximise the radiometric emissivity and the thermal stability, taking into account radiometric
fluctuations of the different parts arising from fluctuations of the reference temperature source.
