Frequency Standard Ch1-53
Also, this device can be called: Ch153, Ch1 53.
Ch1-53 frequency standard is intended for reproduction, storage and delivery of highly stable frequency sinusoidal signals in continuous long-term operation.
Nominal values ​​of the output signals - 0.1 MHz, 1 MHz, 5 MHz.
Voltage outputs 50 Ohm - 1 Vrms.

Frequency standards Ch1-53 are designed as stand-alone device in the case of frameless design. The device is implemented using transistors integrated circuits. The front panel Ch1-53 is a niche in which are placed the indicator and switch control modes, pen correction frequency output signals and toggle charge internal battery. Output signals removed from the connectors on the rear panel.

Specifications:
Frequency correction limits the nominal value - ± 1,25 · 10 -7.
The relative change of the average value of the frequency signal to 1 day:
- After 2 h samoprogreva - ± 5.10 -8;
- After 8 h samoprogreva - ± 2.10 -8;
- After 24 hours of continuous operation - ± 5.10 -9;
- After 1 month of continuous operation - ± 5.10 -10.

RMS random relative frequency variation of the signal after 24 hours of continuous operation:
- 1 s - ± 2.10 -11;
- 10 seconds - ± 2.10 -11.
Temperature coefficient of frequency of 1 ° C - ± 1.10 -10.
Signal / noise ratio in the spectrum of the output signal for network components - 95 dB.

Signal / noise ratio in the spectrum of the output signal to noise measured in the 6 ± 2 Hz:
- Carrier offset 30 Hz - 105 dB;
- Carrier offset 300 Hz - 120 dB;
- Carrier offset 3000 Hz - 135 dB.

The attenuation of the harmonic components of output signals - not less than 40 dB.
Mains voltage - 220 ± 22; 115 ± 5,5 V.
Supply frequency - 50 ± 0,5 Hz from 388 Hz to 428 Hz.
Voltage DC - +27 ± 3 V.

Power consumption frequency standard Ch1-53:
- On heating - 60 · A;
- In steady state - 25 V • A.
Dimensions - 480h120h475 mm.
Mass Ch1-53 frequency standard - 20 kg.

Operating conditions frequency standards:
Temperature - from +5 ° C to +40 ° C.
Relative humidity at +30 ° C - 98%.
Frequency Standard Ch1-53 is used as a working custodian (secondary standard) frequency source model and frequency measuring systems: comparison of frequencies, microwave spectroscopy, Doppler and communication systems.
