Frequency adjusting precision is an important performance indicator of miniaturized rubidium atomic clock (RAC) in some applications. such as the case in GPS disciplined RAC systems. This parameter is determined mainly by the resolution of digital phase-locked loop (PLL) in the frequency multiplier-synthesizer. To improve the frequency adjusting precision of a miniaturized high-perfor... https://yeswellneses.shop/product-category/liquorice/
