Abstract
A method is provided for obtaining a calibration frequency for calibrating a transmission chain that can transmit information signals on a frequency band comprising a plurality of channels. The chain includes an amplifier that can be configured according to at least one gain configuration. The method includes: obtaining an output power value of the amplifier; obtaining a frequency dispersion, based on the power value; detecting whether a constraint linked to said frequency dispersion is satisfied; and if the constraint is not satisfied, then obtaining a current frequency subband and a calibration frequency for said current frequency subband.
