Abstract
A measuring device for suppressing an interference signal contains a mixer, an analog-digital converter, a scaling device and a substitution device. The mixer is embodied to mix a first signal with a first intermediate frequency and to mix a second signal with a second intermediate frequency. The analog-digital converter is embodied to digitize the first signal mixed with the first intermediate frequency to form a first test signal and to digitize the second signal mixed with the second intermediate frequency to form a second test signal is embodied to displace at least the first test signal and/or the second test signal in its frequency in such a manner that they provide a common mid-frequency. The substitution device is embodied to combine the first test signal and the second test signal with a removal of interference-signal peak-value regions which correspond to the interference signal, to form a combined test signal.
