GENERAL.
1-2.
The Hewlett-Packard Model 3300A Function
Generator is a solid state instrument useful for most
general purpose frequency testing applications. Three
output waveforms are available from front panel
connectors; sine, square, and triangle. A sync pulse is
also available from a rear panel connector.

The -hp- Model 3300A Function Generator is a
type of relaxation oscillator.
wave voltage functions are inherent in the oscillatory
system. The sine wave is produced by synthesizing the
triangle wave.

The -hp- Model 3301A Auxiliary Plug-in or
another 3300A plug-in is required to provide internal
connection for basic unit (main frame) operation.

ELECTRONIC FREQUENCY CONTROL.
1-6.
Frequency of the -hp- Model 3300A can be
controlled by either the front panel frequency dial or an
external voltage applied to a rear terminal connector.
This feature is useful for sweeping filters, amplifiers and
other frequency-dependent devices and for externally
programming frequencies for production testing.

linearly control the frequency over any one range (one
decade).
If desired the frequency can be controlled over more
than one decade, by applying a +0.3 to -10 volts to the
FREQUENCY CONTROL BNC. A +0. 3 to -10 V input
will linearly control the frequency over approximately a
50:1 range.

OUTPUT SYSTEM.
1-8.
The -hp- Model 3300A has two completely
separate output channels. Each output is dc coupled
and can be fully floating with respect to power line
ground. An internal shield reduces radiated interference
and provides common mode rejection with floating
output. Separate connectors on the rear panel provide
terminals for circuit ground (

output ground may be floated from power line ground by
up to +250 volts. Any two of the three waveforms are
available simultaneously from the front panel connectors.
