Technical characteristics of the generator G3-7A
    The range of frequencies generated by the following sub-bands:
    1st 20Hz-200Hz;
    2nd 200Hz-2000Hz;
     3rd 2kHz to 20kHz;
    4th 20kHz-200kHz;
    5th 200kHz-500Hz;
    6th 500kHz-1,4 MHz;
    7th-4 MHz 1.4 MHz;
    8th 4MHz-10MHz.
    At each sub-band device G3-7A, except at the 1st sub-band, the stock of Mr. overlap at the edges of at least 5% of the frequency sub-bands at the digitized point. The basic error of the frequency does not exceed ± 2% ± 2 Hz hectare in all frequency ranges.
    Generators G3-7A have the following error of the output voltage at the socket 0-30V:
    - In the frequency range from 30Hz to 5MHz not exceed ± 5% of the nominal value of the relevant range of the instrument;
    - In the range of 20 Hz to 100 Hz and from 5MHz to 10MHz does not exceed ± 10% 'of the nominal value corresponding to the scale of the instrument
    Spurious amplitude modulation of the output signal G3-7A frequencies 1st - 4th sub-bands is not more than 5%. Additional error of the output voltage at the end of the cable attaches to on Mr. ruzochnym resistance does not exceed 15% in the frequency range from 20Hz to 10MHz
    Frequency response unit G3-7A within each subband not exceed:
    - 2D6 in the frequency range from 20Hz to 200kHz;
    - 3dB over the frequency range from 200 kHz to 500 kHz;
    - 3.5 dB in the frequency range from 500 kHz to 1.4 MHz;
    - 4.5 dB in the frequency range from 1.4 MHz to 4 MHz;
    - 7.5 dB in the frequency range from 4MHz to 10MHz.
     Total harmonic distortion at the output voltage up to 30V and load 1000Om not exceed:
    - 3% for frequencies from 20Hz to 20kHz;
    - 5% at frequencies from 20Hz to b0Gts.
    Generators G3-7A allow continuous operation for eight hours, including time samoprogreva. The pre samoprogreva device is no more than an hour. MTBF - 800 minutes.
    Operating conditions G3-7A
