ABSTRACT:
Errors occurring in the beam current measurement in a video output stage can be reduced by increasing the recharging rate of the capacitive load of a video amplifier, constituted by the picture display tube of a picture display arrangement, with the aid of a bias current or a quiescent current which is subtracted again from the current applied to an input of the beam current measuring circuit which is controlled by the video amplifier.
