Beschreibung: Solid State FET Sine Square Wave Generator
                                    The EICO ModeL 379 is a sine and square wave generator that
provides highly stable sinusoidal voltages throughout the
frequency range of 20 Hz to 2 mHz, and square-wave voltages
ranging from 20 Hz to 200 kHz. Designed to generate the
frequencies required for testing all audio and supersonic
equipment, its low distortion sine-wave signals, coupled
with its very sharp square-wave signals, make the Model 379
especially suitable for checking high-fidelity amplifiers
and transducers. This instrument is also ideal for testing
sonar apparatus.
1. The oscillator consists of a low distortion Sultzer
feedback circuit that uses a high-impedance input FET for
increased frequency stability
2. Sine-wave and square-wave voltages are generated
simultaneously at the same frequency, and are made available
at separate output terminals.
3. The output level of each of the two channels is
independent of the other. Each channel is equipped with its
4. The sine-wave output provides continuous coverage of all
the frequencies from 20 Hz to 2 mHz in five bands. The
sinusoidal voltage may be varied from zero to 6. 5 volts
when driving a 600-ohm load.
5. Amplitude variations in the sine-wave signals are
maintained within ±1 db throughout the four lower bands and
±2 db on the highest band. Distortion, rated at 0.25%, is
less than 0.1% over a good portion of the audio spectrum.
The continuous coverage of all frequencies from 20 Hz to 2
mHz makes this -unit ideal for testing speaker systems.
6. The square-wave output can be varied from 0 to 10 volts
peak-to-peak and covers all frequencies from 20 Hz to 200
kHz. These correspond to bands 1 through 4. In band 5, the
square-wave channel is automatically disabled- With a rise
time of less than 0.1 microsecond at 20 kHz, the waveform is
ideally suited for square-wave testing the finest
high-fidelity amplifiers.
7. The instrument power supply incorporates a power
transformer for maximum safety, eliminating shock hazard.
