Sound generator G3-34
Also, this device can be called: G334, G3 34, G-334, GЗ-34, GЗ 34, G З34, G-З34.
Sound generator G3-34 is the source of audio frequency sinusoidal and measuring gene tor intended for adjusting and testing of low-frequency radio equipment cascades.
Oscillator frequency range - 20 Hz to 20,000 Hz.
Frequency oscillator error - ±(0,02 F +1) Hz.
Normal output - 0.5 watts.
Maximum output power - 5 watts.
Sound generator design G3-34 consists of three blocks located on different chassis at an angle of 90° C to a lower gear. The lower horizontal chassis is a master oscillator and an output device, which are separated by a partition. The right vertical chassis output amplifier located on the left - the power supply and a voltmeter.
The whole range is covered by three subbands from 20 Hz to 200 Hz from 200 Hz to 2,000 Hz and 2,000 Hz to 20,000 Hz.
Harmonic distortion at 600 ohms connected to the output attenuator:
- When the output power of 0.5 watts at frequencies from 400 Hz to 5000 Hz - 0.3%;
- At frequencies from 50 Hz to 390 Hz, 5.1 kHz to 20 kHz - 0.7%;
- At an output power of 5 W at frequencies from 60 Hz to 20 000 Hz - 3%.
Power consumption - 150·A.
Continuous operation time - 8 hours.
Warm-up time - 30 minutes.
Uptime - 1000 hrs.
Dimensions - 550x350x360 mm.
Weight unit G3-34 - not more than 30 kg.
