Abstract
A method and a device for controlling the level of a pulsed high-frequency signal amplify or respectively attenuate an un-pulsed high-frequency signal with an amplification or attenuation element adjustable with regard to its amplification or attenuation factor. A pulsed high-frequency signal is generated by a pulse modulator controlled by a pulse signal from the un-pulsed high-frequency signal. At the output of the pulse modulator, a signal level of the pulsed high-frequency signal is measured by a high-frequency detector. The amplification or attenuation factor of the amplification or attenuation element is adjusted with a level controller controlled by the measured signal level. To control the level controller, the measured signal level of the pulsed high-frequency signal is linked to the measured signal level of the pulse signal.
