Subject: beat note work and PLL 

Summary

  • Today we have worked reying to improve the beat note signal in its amplitude.
  • We also connected all the parts for the PLL loop and tryied to lock the PLL but we did not succeded;
  • We noticed at some pint a noise at the input of the sr560 which pheraps prevents the PLL lock


    Conclusions

           We need to improve the lock of the cavities in order to get a more stable signal and solve the origin
           of the noise at the input of the sr560 in order to lock the PLL.
