Model AF-712 . Oscillator is an economical but versatile sine and square wave generator for Audio and supersonic frequencies between 20 Hz and 200 KHz. It is suitable for measurement of frequency and distortion of Audio and wide band filters and transmission systems.
The design employs Wien Bridge circuit. The output impedance of the Oscillator is low, thus minimizing effects of loading with good regulation.
The instrument is housed in an angle – aluminum cabinet duly painted.
