- Adopting infinitely timing with large adjustment range.
- Adjusting range is earth 4 diopter.
- The experimental results showthat the frequency adjustment range of the filter is in excess of 3 dec-ades.
- Thus the adjustment mechanism can meet the requirements of large adjustment range and nano-radian resolution.
- Uses import frequency conversion stepless speed, the adjustment range is wide, the precision is high, and start-up moment is large.
