Instruments for adjusting and controlling the PTA.The generator of standard signals "G4-18" has been produced since the beginning of 1965 by the Gorky Frunze Plant, and the generator "G4-18A" since 1971 by the Kaunas Research Institute of Radio Measuring Equipment. The generator of standard signals "G4-18" is designed for tuning various radio receiving equipment. The range of generated frequencies - 100 kHz ... 35 MHz is divided into 6 sub-bands. Until 1965, the plant produced a similar generator, but under the name "GSS-41". The generator of standard signals "G4-18A", produced from the 1st quarter of 1971, differed from the generator "G4-18" only in a more modern design.
