    Frequency counter Ch3-44 (Ch3 44, Ch 3-44, Ch 44 3, Ch-3-44, Ch-3 44)
    Frequency counter Ch3-44 - a device designed to automatically measure the frequency sinusoidal electrical signals and issuing kvartsovannoy voltage frequency.
    Frequency range - 100 kHz - 60 MHz.
    - 10mV - 10V - when a signal directly to the input of the device;
    - 1V - 100V - with an external attenuator probe.
    Power consumption - 60W.
    Dimensions - 320 × 165 × 327mm.
    Weight - 7.5 kg.
    Frequency Ch3-44 used to configure, test, and calibrate the various paths of transceivers, filters, oscillators, as well as setting of communication systems and other devices.
    Specifications Ch3-44

   Frequency counter Ch3-44 can operate with an external signal source standard frequency 1 MHz (effective voltage from 0.5V to 3V at 100 ohms load) instead of the internal crystal oscillator.
    Frequency counter Ch3-44 has an input impedance at least 1 Mohm, input capacitance - 30pF more. The device provides its specifications relative accuracy crystal oscillator frequency is not more than ± 1 × 10 -5 after heating for 15 minutes.

    Start-up time frequency Ch3-44 with a relative error of the crystal oscillator frequency to 10 -4 or by the unit to an external standard frequency - less than 1min.

Frequency counter Ch3-44 is powered via an AC voltage of 220V ± 22V and a frequency of 50 Hz ± 0,5 Hz and AC voltage of 220V or 115V ± 11V, 75V and a frequency of 400 Hz.

Permissible harmonic content - up to 5%.
MTBF Ch3-44 - not less than 1500 hours. Service life - at least 10 years of age; technical resource - 10,000 hours.

     Frequency counter Ch3-44 are designed for use in the following conditions:
    - The ambient temperature from -30 ° C to +50 ° C;
    - Relative humidity - 98% (at ambient temperature to +35 ° C).
    The manufacturer guarantees that the frequency corresponding to Ch3-44 e t the technical requirements specifications subject to the consumer the terms and conditions of storage, transportation, installation, operation, established specifications and operational documentation.
