IG-1272 AUDIO GENERATOR

The Heathkit IG-1272 Audio Generator can generate an
audio sine wave from 5 Hz up to 100 kHz. Frequency is
selected through the use of three banks of selector
pushbuttons, giving an accuracy of three places, and a
variable frequency control is available for fine tuning.
A set of four frequency decade multiplier pushbuttons sets
the frequency scale. There are three pushbuttons set for
10, 20, and 40 dB fixed attenuation along with a variable
level control. A front panel meter reads the output voltage.
The output is switchable from an external load to a 600 ohm 
nternal load.
