To do this, prepare the calibraZon set (open circuit, short circuit, 50 Ω). • Oscillator adjustment : Set the frequency to 27,000 MHz with the Generator and measure the frequency with the frequency counter or receiver. With Se<ngs> ConfiguraBon with Next Param, select parameter SI5351_CORR and enter the previously measured DeviaBon in Hertz. Page of 1 16
