Frequency divider unit Ya3Ch-51 (Ya3Ch51, Ya3Ch 51, YaZCh-51, YaZCh 51)
 
Frequency divider unit Ya3Ch-51 is a plug-in unit of frequency for electron-counting (BSEC) H3-34 and Q3-34A (later H3-34) and is intended to extend the range of measured frequencies of up to 120MGts 4500MGts;
The unit is intended for use in non-heated surface and underground facilities.
If you are working in countries with tropical climates recommended unit operation in rooms with air conditioning.
In the case of operation of the device frequency divider unit YaZCh-51 in a humid tropical climate in the ordinary room conditions without air conditioning should include an additional block with the frequency counter for at least two hours to warm it.
 
Technical characteristics of the devices power frequency divider Ya3Ch-51:
 
Conditions of operation of the device:
- Ambient temperature - from -30 ° C to +50 ° C;
- Maximum ambient temperature - from -50 ° C to +65 ° C;
- Maximum relative humidity lower than 98% at temperatures up to +35 ° C;
The range of measured device frequency divider unit Ya3Ch-51 frequencies - from 120MGts to 4500MGts;
The minimum input signal level, no more than:
- 50mV - ranging from 1000MHz to 120MGts;
- 100mkVt - ranging from 1000MHz to 3000MHz;
- 500mkVt - ranging from 3000MHz to 4500MGts;
Maximum input level device frequency divider unit Ya3Ch-51:
- 1B - in the range of up to 1000MHz 120Mgts;
- 50mW - ranging from 1000MHz to 3000MHz;
- 15mVt - ranging from 3000MHz to 4500MGts;
Input Impedance - 50 ohms ± 5 ohms;
The time for establishing the timing mode, the device frequency divider unit YaZCh-51 - no more than 2c;
Accuracy of frequency measurement frequency counter with a block of the frequency divider is equal to the error of frequency measurement is determined by the actual frequency meter and the following dependencies:
- The basic relative error in percent:
 
δ ƒ ≤ ± (δ a + (I / ƒ ∙ t ism cq)) ∙ 100
 
where δ a - the main source of relative error of the reference frequency used by the frequency meter; ƒ ism - measured by the device frequency divider unit Ya3Ch-51 frequency in Hz; t cq - counting time in seconds;
- Additional relative error in percent:
 
δ ƒ ext = δ of extra ∙ 100
 
where δ of ext. - an additional source of error in the reference frequency, frequency meter is used, when the ambient temperature;
Footnote. When measuring the frequency of using the device frequency divider unit Ya3Ch-51 selected measurement time equal to the value given against the provisions of the corresponding switch "measurement time" the frequency is increased to n times the value of n can take values ​​of natural numbers from 2 to 128;
MTBF device frequency divider unit Ya3Ch-51 must be at least 2250 hours;
Unit allows continuous operation of the device in conjunction with H3-34 under the operating conditions for 16 hours, while maintaining performance;
Dimensions - 141X142X282mm;
Weight of the device unit Ya3Ch-51 frequency divider without spare parts and packaging - no more than 4 kg;
Warm-up time unit - no more than 5 minutes.
The manufacturer guarantees the quality of the device frequency divider unit YaZCh-51 technical requirements specifications, subject to the consumer the terms and conditions of storage, transportation, installation, operation, established specifications and operational documents.
