Informazioni:
                                    The Model 3020 Sweep/Function Generator is the most
versatile signal source ever offered by B & K-PRECISION. It
combines the operation of four instruments into one —
function generator, pulse generator, sweep generator, and
tone burst generator. With this versatility, it has a vast
number of applications in both analog and digital
electronics in the engineering, manufacturing, servicing,
educational, and hobbyist fields.
The heart of the function generator is a VCG
(voltage-controlled generator) that produces precision sine,
square, or triangle waves over the .02 Hz to 2 MHz range.
This encompasses subaudible, audio, ultrasonic, and RF
applications. A continuously variable DC offset allows the
output to be injected directly into circuits at the correct
bias level.
Variable symmetry of the output waveforms converts the
instrument to a pulse generator capable of generating
rectangular waves or pulses, ramp or sawtooth waves, and
slewed sine waves of variable duty cycle. All waveforms can
be inverted.
The sweep generator offers linear or log sweep with variable
sweep rate and sweep width up to 1000:1 frequency change.
This allows one continuous sweep to cover the entire 20 to
20,000 Hz audio band. The frequency response of any active
or passive device up to 2 MHz can be determined.
The tone burst generator chops the output into alternate on
and off periods. Both the repetition rate and on/off duty
cycle are variable. Tone burst testing is essential for
speaker acoustics measurement, modulation limiter attack
time measurement, tone burst decoder alignment, and many
other applications. The tone burst is in integral half
cycles of the frequency being gated. This allows
synchronization of the waveform for oscilloscope viewing and
eliminates transients and frequency components not
harmonically related to the frequency being gated.
In addition to all the above features, an external signal
may be applied to achieve amplitude modulation. Percentage
of modulation is fully adjustable; also, the carrier can be
suppressed to obtain a double-sideband, suppressed carrier
signal. Most functions can be generated simultaneously; thus
it is possible to test effects of simultaneous AM and FM
modulation, or to sweep during tone bursts.

Further versatility is possible with external tone burst
gating and external control of the VCG for operation such as
programmable frequency control, FSK, and sweeping or FM’ing
to an external control signal.

A fixed level TTL output is available in addition to the
adjustable amplitude 50-ohm output, which can be varied from
20 millivolts to 20 volts peak-to-peak open circuit (10
millivolts to 10 volts peak-to-peak into 50 ohms). A sample
of the generator control voltage (GCV) is also available for
external use, such as horizontal sweep of an oscilloscope
during sweep alignment or frequency response measurements.
