The LAB A.F.OSCILLATOR, Model AFO-1, is a very useful laboratory instrument and is a source of pure sine wave and square waves. It is intended primarily to test, measure audio equipment parameters, such as input sensitivity, frequency response, stage gain, distortion and power.

It can be used to test or service any audio devices, like microphones, loudspeaker, pickups, amplifiers, etc.

It can also be used as a tone generator and to modulate RF signals. The square waves are intended to determine frequency response and harmonic distortion quickly. Square-wave testing of amplifier is a modern and easier method.

This instrument is completely an IC version and generates frequencies, from 2Hz to 200KHZ in five decade ranges. The output voltage can be varied continuously upto 10 volts (peak) Into 150 ohms. The distortion is less than 0.5 percent.

The rise time of the square wave is less than 50 nano seconds. This instrument is housed in a sturdy metal cabinet, which is light in weight,
