Abstract
A measuring device provides a synthesizer device, at least two controlling devices and at least two controlled oscillators. The synthesizer device contains at least one direct digital synthesizer and generates at least two signals of known phase ratio. Signals generated by the synthesizer device form reference signals of at least one controlling device. Signals formed by the controlling devices control the controlled oscillators. The measuring device contains only frequency splitters, which divide by integer division factors.
