General
LSG-17
is
a very versatile thick film integrated circuit (IC), wide-
band
signal generator designed for
the
radio experimenter, hobbyist,
service technician and instructional purposes. An IC
is
used in a stable
oscillator circuit
to
cover the frequency range from 100kHz
to
150MHz
on
fundamentals and
up
to
450MHz on harmonics. Among
the
many
features are
the
large easy-to-read dial marked
at
455kHz and
10.7MHz, one audio frequency for amplitude modulation
or
external
use, provision for crystal oscillator operation. Serves
as
a marker
generator when used with a sweep generator in checking and aligning
RF
and
IF
circuits in TV and FM receivers.
