A method for digitally compensating variations, as a function of temperature, of an electrical quantity of an embedded space radiofrequency telecommunications equipment item, the equipment item comprising N individual devices, where N is greater than or equal to one, the electrical quantity of the equipment item having to be maintained at a predetermined setpoint value, the method comprising, in order:
- measuring the temperature of the equipment item at different measurement instants,
- at each measurement instant, in interrogating look-up tables, respectively dedicated to different setpoint values, in which digital control words are stored that are to be applied to the equipment item as a function of different digital temperature states corresponding to different measured temperature values,
- when the measured temperature is situated between two digital temperature states stored in the look-up tables, in creating intermediate digital temperature states situated between the two stored digital temperature states and in computing, by interpolation, digital control words corresponding to the intermediate digital temperature states created,
- creating, by interpolation between two stored digital control words, intermediate digital control words coded on a number of bits greater than the number of bits of the stored digital control words,
- selecting a digital control word corresponding to the measured temperature, and delivering, to the equipment item, an analogue control corresponding to the selected digital control word.
