摘要： In an exemplary embodiment, several measuring channels include amplifier circuits subject to zero point drift during measuring signal interruptions. For each measuring channel of the radiation receiver, a register comprising a plurality of memory locations for correction values is present, whose input is connected to the measuring channel output following the amplifier circuit and whose output is connected to the measuring channel input in front of the amplifier circuit. Each register supplies to the associated measuring channel input a correction signal having a value in dependence upon the measuring channel output signal during a preceding signal interruption and such as to correct for any zero point drift of the amplifier circuit.
