Structural features Ch1-50
The standard frequency of Ch1-50 uses solid-state devices and circuits, as well as built-in battery backup power. These components provide high reliability of operation.
For ease of use, frequency standards, Ch1-50 have a semi-automatic system monitoring and fault detection, which provides light alarm if there is excessive regulation of the error-locked, in case of failure of the system thermostat, rubidium discriminator element path of a self-tuning, the transition is powered by internal batteries.
Standard frequency Ch1-50 allows the actual value of the frequency error of ± 1 × 10 -10. The relative systematic change in the frequency signal for 30 days does not exceed 6 × 10 -11.
The rms variation of the relative frequency of the signal frequency standard Ch1-50 has the following values:
- 3 × 10 -11 (averaging time 1);
- 2 × 10 -11 (averaging time 10 s and 24 h).
Standard frequency Ch1-50 allows these types of attenuation:
- The network components of the output signal of 5 MHz - no more than 80 dB;
- The noise components in the range 30Hz - 10kHz band and 6Hz analysis - no less than 100 dB.
The limits of the frequency adjustment - ± 1,9 × 10 -9.
