Description: Audio Generator
                                    Based on a highly reliable circuit, the Model 378 Audio
Generator produces a very low distortion sine wave signal
over a very wide range of frequencies and is ideal for use
in testing audio amplifiers for gain and frequency response,
as a signal source for various bridge measuring circuits,
for modulation of RF signal generators, or any other
application where a stable, accurate audio sine wave must be
Unlike most other audio generators that require
interpretation of a dial setting with possible error, the
frequency-determining elements of the Model 378 are not
continuously variable, but are set by positive-setting
detent switches that selects combinations of 1% resistors
and 2% capacitors that make up the frequency-selecting
network. This method of tuning enables repeatable accurate
setting to any individual cycle between 1 cps and HOkc.
The output level of this instrument can be set with great
accuracy between 0 and 10 volts RMS (or between -70 and
+22db) ön a 4-1/2 inch, 2% full-scale accuracy meter.
Below 1 volt RMS output, the instrument is provided with a
switch-selected internal 600Ω load that can be disconnected
as desired.
