Аннотация:The world around us depends on devices capable of producing or maintaining a
signal with an extreme precision. Quantum frequency standards are the answer to this problem.
This article presents a modified version of newly developed quantum frequency standard based
on trapping Hg-199 ions by magnetic field. The new prototype was developed a while ago and
now it was modified due to algorithm improvements and renewed digital hardware, analog and
digital circuitry being reordered. Results for Allan deviation show 3 % improvement for longterm frequency stability and more than 5 % for short-term stability
