Signal generator '' G3-7A '' (G4-65A).
Instruments for adjusting and controlling the PTA.The signal generator "G3-7A" was produced presumably since 1960. Since 1949, the "GS-100" generator has been produced, a complete analogue of the "G3-7A" generator. Since 1972, an analogue according to the electrical circuit and TX has also been produced, in addition to a more modern design, a high-frequency signal generator "G4-65A". The signal generator is designed to tune various broadband video signal systems. The frequency range 20 Hz - 10 MHz is covered by 8 sub-bands. The high-frequency output voltage is infinitely adjustable from 0 to 30 volts. Dimensions of the generator "G3-7A" - 540x370x370 mm. Its weight is 30 kg.
