STL-CS Universal Low Phase Noise Frequency Source
STL-CS Universal Low Phase Noise Frequency Source
  The STL-CS series universal frequency source utilizes direct digital frequency synthesizer technology, providing users with an additional frequency stability of better than 2E-13/s for arbitrary frequency signals ranging from 0.5M to 120M. The frequency adjustment resolution of this device is ≤1μHz, which allows users to quickly output various frequency signals. It is the best choice for AOM and EOM driving, as well as scientific research.
