Hydrogen Masers
● Hydrogen Maser is designed to operate as a source of high-stability, high-accuracy and spectrally pure frequency and timing signals (5 / 10 / 100 MHz sinusoidal signals and pulses with 1 s period).
● Main application fields of the Instrument are metrology, time keeping & precision time scaling, frequency reference source, global positioning / navigation satellite systems (BD/ GPS/ GNSS), deep space tracking, radio astronomy with very long baseline interferometry / array (VLBI / VLBA).
● World Top Level Temperature Sensitivity:  CH1-95:≤1,5 × 10–15/°C (typical: 0.5 × 10–15/°C), 
CH1-75A: ≤ 2.0 × 10–15/°C, 
CH1-76A: ≤2 × 10–14/°C
