Low-frequency generator `` GRN-1 ''.

Instruments for adjusting and controlling the PTA.The low-frequency generator "GRN-1" has been produced by the Vilnius plant RIP since 1985. The generator is used in amateur radio practice when setting up low-frequency devices. The generated frequency range is 20 Hz - 200 kHz. The frequency setting accuracy is 3%. Harmonic coefficient 3%. Uneven frequency response in the frequency band - 0.8 dB. The maximum output voltage at a load of 600 Ohm is 0.5 V. Power supply ~ 220 V.
