ABSTRACT:
Attenuation arrangement comprising a step attenuator arranged in cascade with a controllable voltage divider via first and second voltage terminals, the step attenuator comprising a series arrangement of attenuation elements for dividing a voltage applied across said series arrangement into a plurality of voltage increments, which voltage increments are individually switchable between the two voltage terminals for varying the output voltage of the controllable voltage divider for the voltage range of the relevant voltage element, the direction of the polarity of the voltage between the two voltage terminals changing at a switch-over from one voltage increment to an adjacent voltage increment.
