Abstract
An attenuator system for adjusting the output of an HF signal source is described in which, between the signal source and an output, an electronic attenuator is disposed via mechanical switches on the input and output side. The mechanical switches can be switched in such a manner that, in one switch position, the electronic attenuator is inserted between the signal source and the output, and in the other switch position, a direct bypass is inserted between the signal source and the output.
