Technical characteristics
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.

Description of the instruments taken from the technical documentation or technical literature. Most pictures of products made directly by our experts prior to shipment of goods. In the description of the device provided the main technical characteristics of the instrument: nominal measuring range, accuracy class, scale, supply voltage, size (size), weight. If the site you see the discrepancy device name (model) specifications, photo or documents attached - let us know - you will get a useful gift with-selling device.
While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.
In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.
On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.
All text and graphic information on the site is informative. The color, shade, material, geometric dimensions, weight, content, delivery set and other parameters of the goods presented on the site may vary depending on the batch of production and year of manufacture. Check with the sales department for more information.
