GENERAL INFORMATION
INTRODUCTION
The A0-3001C sinewave oscillator oscillated the audio signal in frequency from 10Hz to
1 MHz in 5 overlapping ranges.
In most measurements, this oscillator can be used without a external frequency counter
because the output frequency is direct readout by 4digit green L.E.D display.
The oscillator has a push button key S. W for range selection and the easy operable step
attenuator.
This compact and light weight instrument is very useful for R&D laboratories, factory, and
field service of various electronic equipment as a signal source for high performance audio
instruments.
