RUBIDIUM REFERENCE OSCILLATORS AND RUBIDIUM FREQUENCY STANDARDS,
MEASURING EQUIPMENT, DEVELOPMENT AND PRODUCTION
Small-sized Rubidium Reference Oscillators and Rubidium Frequency Standards
Rubidium Frequency Standard CH1-1014

CH1-1014 has the same applications as CH1-1013.
CH 1-1014 has output frequency correction with 1 s signal from outer time scale or GPS/GLONASS receiver.
CH 1-1014 has controlled frequency synthesizer for digital output frequency adjustment in range of ± 1.10-9 with resolution of 1.10-12


 

  • High frequency stability
  • Low environmental sensitivity
  • Frequency adjustment with GPS/GLONASS receiver
  • Diagnostic system and digital control through serial RS -232.
