Abstract
A pulsed radar level gauge for determining the filling level of a product contained in a tank, comprising a frequency generator for generating a Tx frequency signal and a Rx frequency signal. The frequency generator includes one single oscillating crystal for providing an oscillator frequency fand frequency modifying circuitry. The frequency modifying circuitry comprises a path including a PLL configured to receive said oscillator frequency fas input frequency and deliver a regulated output frequency being equal to the oscillator frequency fmultiplied M/N, and a frequency divider connected to receive the regulated output frequency and deliver an output frequency equal to the regulated output frequency divided by an integer factor P. A PLL combined with an integer frequency divider is used to generate at least one of the Tx and Rx frequencies based on an oscillator frequency provided by one single oscillator.
